Sir when you are uploading this video in Hindi language
Thanks Raul
can u make a separate video about semi-conductor
i am very much confused o this topic
so when u order, can u get thw components also from them?
@@mohammedsaad3503 jlcpcb has another company named lcsc. In the ordering section on jlcpcb.com, you can upload the BOM file, which contains the components that you need. In addition, you can order your pcb with the components soldered on them according to your schematic file.
Back in time, I became independent. I started my own business designing electronic test equipment, to test assembled PCB circuits. But I was so poor that I had to use freeware to do the job. I had to create PCB's in the process but the freeware PCB design software only allowed a limited amount of components. It also allowed you to create your own components. So I would design a portion of the PCB layout, and then due to having reached the maximum amount of components allowed, resistors, capacitors, transistors, etc, I created a new component which in truth was a combination of all the components used so far, and their specific layout. Yep, when you are poor, you find a way around everything. Anyhow, one company was so impressed with my work that they hired me full time. Eventually I was also designing high voltage power supplies for neon sings as well as designing the test equipment to test them at the assembled PCB level. Not bad for a grade ten dropout. I had no education in electronics, but was self taught.
Thanks for the inspiration
Use Kicad, it's free
@@ahmadwahyudin5196 he says back in time not now
@@akashghosh1151 oh sorry, my mistake
Your story resonates with myself. Having no grades doesn't mean your not capable achieving and learning to reach your goals.
This only means we have different learning pattern that schools don't teach. But it also means we are capable to find solutions faster by thinking out of the box.
Thanks for sharing your story and inspiring others. 👍
Holy crap this is the most impressive and comprehensive tutorial I have ever seen on youtube. The organization, the speed that you go from topic to topic, the thoroughness of the design, and software use even shipping? Incredible.
Love the way you explain everything and we get everything.
all greek to me
yep bc greek is my first language :)
Thanks to your video i was able to make my first actual circuit board! I didn’t do the fancy printed board thing but i had some blank pcb boards and was able to recreate this regulator as my very first circuit board! Im only 18 and have been interested in/ making electrical things (lights mainly) but your videos explain how components work and how to use them in real world applications. Thank you so much for putting the time into making your videos so well thought and so well explained. To help people such as myself follow their passions or dreams easily building circuits without having to go to school for it or destroying components trying to figure stuff out based on less helpful videos. Cheers! 🥂 🍻
i can only say THANKS, because the way you explain is so clear and rapid... Please continue to do projects like this because I have never undestand electronics faster!!
I implemented this project front to back with success, and fabricated Paul’s Gerber files, too. This video was so well put together.
This tutorial on CZcams is incredibly impressive and comprehensive. I'm amazed by how well-organized it is, the perfect pace at which you cover various topics, and the depth of detail in design and software use, even including shipping. It's incredible that you also provide resources for free; as a student, I find this incredibly beneficial. Thank you so much for this helpful content, and many thanks for your generosity.
absolutely fantastic way to transfer knowledge, well done, so .... comprehensive. esp love the 'hey this might work too for this reason, but this is fine' element. teaches me so much more as it gives me a scale of the subject/component/concept
Excellent video. Love the design software and custom printed PCB. Back in the 80's when I used to play with electronics I either used the boards from Radio Shack with tons of holes, or I hand-drew a PCB and etched it myself with one of their kits.
Radio shack, miss that place
ur such a good teacher man i learn so much so quick yet not in an overwhelming way you for sure have an invaluable skill
This is the best Electronics and Engineering channel on CZcams. Without a doubt. All videos are clear, objective so as not to leave any "loose ends" that could create confusion. I was very happy to find this channel. Many questions that I have come here and resolve. That simple.
Thank you !🙏🙏🙏🙏🙏🙏
Impressive explanation...7805 always remain the top priority and almost have one since 2010, when i first started my own design.
I want to truly thank you for your videos , I am a french student in preparatory classes and you explained very well how electrical component (inductor ,capacitor ...) work with simple explication ( water tank...) you help us a lots (i just start the électromagnétism i wait your videos on it :) ).
This regulator project was amazing thank you and go on :)
Glad they help yoi
Thank you so much ! but we need more projects like this in order to apply what we have learned ! I think everyone agree on that :D
This is the BEST video you have ever made! I love all of your videos but learning to make your circuits a reality is the most amazing thing ever you have no idea!!!
The best circuit designing A to Z using Altium I have ever seen on CZcams 👍🏻👍🏻
The explanation was outclass. You motivated me to design my own voltage regulator like you did. Thanks man. God bless you
Designing a voltage regulator is not as hard as it seems. Especially, if you have a basic understanding of circuits and some electrical components. After watching a few online tutorials, I decided to give it a try. The end result was a functioning voltage regulator circuit that met my needs.
I must admit that I was motivated to design my own voltage regulator after watching one of your videos. Your explanation was outclass.
Love the way you teach😍: first explaining circuit, then design, then using design app.
Very good, I hope you continue this way. 🙏
Great job and I especially like the way you added the Altium tutorial in for the PCB design. I'm working with Altium now and it's a great help.
This channel is awesome! I’m 34 and getting into Arduino. Your channel is very helpful in explaining the process as well as entertaining with new ideas and stuff. Thank you!
"Click Auto-route" is an on-going joke at my job. Worked out well for you though!
Where do you work? Pcb manufacturer?
@@michaeld9682 No, I work in product development and regularly have to review PCB layouts.
Sometimes on larger PCBs I'm working on I'll hit auto-route just to see how ridiculous it gets lol
hahahaha I laughed hard! Since the circuit is basic on the video, he did that ya know :)
@@jmannUSMC if you write your drc properly, auto route always works and saves me the pain of routing 100 components manually like a laborer when I have software provided edge
great tutorial. explaining the functionality of each component was the best part form me. thank you for sharing
Thanks for the great tutorial, I just ordered the voltage regulator PCB and my students will be building them soon. Thanks again.
I'm an architectural engineer...but I love your work and way of explanation...Great work....
This is one of the best videos I've ever watched 🔥🔥. You killed many birds with one stone, by explaining different aspects in a way that makes the process seam easy, starting from components' operation, circuit design, to PCB fabrication. Lots of love for the great work you're doing.
I don't have the proper words to express how good this video is.
i doCRAP
@@deansmith4752 why?
Me too
You're best teacher I've ever seen, please continue and make a video about more complex PCBs...regards
glad i put this video in a favourites folder, this is exactly what i am needing to build, 5v and 10v versions with leds and switches, thanks
Hai bro I am second year electrical engineering student but never feels like I am studying electrical engineering
Just books books no lab is possible because of online teaching even if we have our lab practicals we don't have goodlab technicians so we just go there for grades but you are amazing thank you . by watching your videos now I think lab and electrical eng also intersting
To put it simply, you're brilliant!
You my brother, have the best explanations in the world. May you be blessed for life !
This teacher is much better than my school teacher. Best electronic yt channel on youtube. Thank you.
That was a brilliant video, I love that PCB design software. I used to do it by hand in the mid 80's and the tapework as well all by hand. We made the artwork twice the size so it was easier to tape then the original would be reduced to half size by copier then ready for printing to PCB. That was the best job I ever had, I even say that over 30yrs later. . All we were given was a circuit design from some big company on a piece of paper, I even had a small diagram on a piece of card. We had to design everything ourselves, I loved it.
I lost interest in computers years ago but I would love to learn that system you have there, its brilliant.
Good work 😊😊
I did it so in the 70th
Paul thanks for everything. I have learned lots of useful things about my profession more than I learned from university. Your channel is AMAZING... and please make a video about solar energy systems🙏
I never knew how a voltage regulator worked before I started watching your channel. I also learned about linear regulators and how to choose the right one for a specific application. I now know more about my profession than I ever did from university. Thank you for making these videos!
you will learn how to make a 5V regulator using capacitors, LM7805 regulator and Schottky diode. This circuit works by converting the unregulated voltage from the battery into a regulated 5V output. The capacitors smooth out the voltage fluctuations, while the LM7805 regulator ensures a stable 5V output. The Schottky diode protects the circuit from reverse polarity connection and also increases efficiency.

Pretty cool video, you explain things so clearly. Electricity is so fascinating...
Incredible video ... i am not an engineer but i watch these videos .. because i really love it. Thanks for posting them. 🤗
Best channel on the entire internet right here, it’s true. Always more to learn.
Buck and boost circuits amplify the complexity. I would love to see him do a vid on those
Great video, really i have get benefit of it. Next video we need overcurrent protection circuit .
Thank you so much for your exerts.
This is the meatiest electronics video I've seen to date. Although you do an excellent job presenting this material, you tend to go just a bit too fast for my brain to comprehend. I guess that's why they invented the PAUSE button. I'm so glad someone took me by the hand to show me how I can actually take my creation and turn it into a professional looking Printed Circuit Board. And for that, I am forever in your debt. Thank you from across the pond here in the U.S.
Oh, nooo... I was looking for such a channel for long. After watching the video I immediately subscribed. Please keep all your videos as simple as possible.
Nice videos, and also really well explained. Please continue making this kind of videos that really helps a lot to those who want learn something new the best vibes for you
In this video, we're going to take a look at a voltage regulator circuit. This is a very important circuit, and it's used to maintain a constant voltage output despite changes in the input voltage. This is useful for things like powering microcontrollers, or other sensitive electronics.
The basic principle of the voltage regulator circuit is simple. We have an input voltage, which is applied to the Vin pin of the regulator. The regulator then outputs a constant voltage on the Vout pin. This voltage is regulated by the feedback resistor Rfb.
The regulation of the output voltage occurs because of the way that transistors Q1 and Q2 are connected. Transistor Q1 acts as an amplifier, while transistor Q2 acts as a switch. When Vin is greater than Vout, transistor Q1 is turned on and transistor Q2 is turned off.

Great vid, I was looking for such a device, we have gas BBQs that I installed with micro solar panels to charge the igniter, I ran into a problem when the cloud cover changed to output voltage it would trip out the controller for the gas flow, I think this might be the answer to keep a constant voltage from the battery to the units circuit.
Thanks from downunder 🇦🇺👍

Excellent Video ever! It has everything we need in a clear and easy-to-understand way. I'm really impressed by it. I must say, this video is exactly what we're looking for. Great Work👏@The Engineering Mindset
You give perfect knowledge as compared to colleges give .Thank you so much for making this video and make more videos like this👍🏻
Great video! It would be great to explain to beginners the principle of why the values of those capacitors are used. Or else, you are just teaching someone to copy a design and not design it themselves.
This was a great video about regulating voltage with the 7805. I wonder if you are also going to make a video about buck converters or SMPS.
Plenty more coming
Excellent video, very well explained and also entertaining ! Great job, well done !
Just wanted to pop in real quick to shout out, I ABSOLUTELY LOVE THIS CHANNEL!! 😃👍🏻
Buck boost modules vs regulator ics. Need a lecture on this
used a 1.00uF capacitor instead of the 0.22 since i didn’t have one, still works perfectly. Powered with a 9V battery and output is 5.01V as desired. Made a similar circuit before without a diode and with only 2 capacitors instead of 4.
You can connect DC to a 7805 directly, no need for any extra components, those are just recommendations, but I've only ever used it on it's own and a battery for any logical gates circuits, which can only work with 5v.
@@Freixenetynt yes i know. the capacitors just help filter out any noise in the circuit
it's an outstanding tutorial everything is sound thump up bro.....i did it 20 yrs ago n it came up straight away well done cant wait what else I will discover.
I make military and other complex PCB's for a living, love your stuff!
Dear God. That software tutorial was like learning German. Time for me to hire a tutor! Lol
Like eagle software
That software was just bad, I'm sure there are better ones that are more user friendly.
@@Othman1992on and don't cost an arm and a leg, like Altium
For polarity protection, I'd use small bridge rectifier. Then you can even supply ac to circuit.
Could you please help me how to add few more components into it and how can I get multiple outputs from it from different points. For eg 5v 3v etc
A voltage regulator circuit is a great way to ensure a steady flow of power to your project. However, if you're using an AC adapter to power your project, you'll need to use a bridge rectifier to protect your regulator from polarity reversal. Without a bridge rectifier, your regulator may be damaged if the polarity of the input voltage changes.
@@SFORSANDEEP you need a 2510 bridge rectifier at the input side and a variable resistor or potentiometer at the output side

Today I learned how to design a PCB board and get it made. Thanks so much. :)
Excellent video, very talented at breaking down terms that an average tech can understand!
Belíssimo! Show de bola.
A small solar panel as the input voltage would be sweet.
Probably need a few solar cells, need to input +7V minimum, but it would work
Voltage regulators are inefficient and only work with higher voltage. Think of it this way "Where does all the extra voltage go?
@Joachim Shekelberg wasted electricity is never a good thing
@Joachim Shekelberg what circuit do you use , any linear regulator always have dropout votage
Not realy, this curcuit doesnt take advantage of a solar panel power changes trow the day
You are a brilliant mind 🧠 all the way from South Africa, much appreciated.
very inspiring, my guy just summarized my 4 yrs in high school that was spent in studying physics in explaining the fundamentals of electricity under 10 mins, as well as condensed my 5 years in campus that I spent chasing a degree in electronics under the pcb section as well as 2 extra years of entrepreneurship by taking us through the ordering system from jlcpcb. Ill never forget this degree of insult
This is next level tutoring right here - if this kind of quality content existed when i was meandering my way through grade school, I would have had my seat firmly planted in those classroom benches instead of chasing dirty $kankz and booze 😂
Thank you for making this video and sharing all the info and files, it is very inspiring!
Wow amazing mind blowing as always, my knowledge expanded greatly . Well appreciated. Thank you very much
There should be a heatsink attached with the voltage regulator though.
Remember that W=V*I. Meaning, if you have higher voltage input (say 24V) but output is only 5V and you're drawing only 0.2A then the linear voltage regulator has to dissipate about ( 24V - 5V ) * 0.2A = 3.8W as waste heat. It will get quite hot quite fast. Times like that - consider if buck regulator would be better option, if not for the noise/EM interference that accompanies it.
I would turn the voltage regulator 90 degrees and place it near edge. Another possibility would be placing it flat on the other side (there are more options). It all depends on how you are planning to connect it to the heatsink and/or how much heat you need to dissipate.
Based on the datasheet, at 25°C ambient, you can draw 6.58W. That's 1.32A. Keep in mind that's at 25V. If your input was 12V or 9V, which is typical, you can easily achieve 1.5A without a heat sink. However, I would use a heat sink to dissipate heat through a sealed case to reduce heat building up, which might affect other components.
JLCPCB is amazing, Ive had almost 1000 pcbs made from them and they are all really nice.
You explained this better than all the professors in my supposedly "TOP" University.
Have always been interested in these but got impotent people to learn from sadly.
Take note that the capacitors have values based on the expected loads/ power deraws of the circuit, also make sure the diodes use have a smaller break voltage then the voltage source u are using
@@kennmossman8701 almost never but i had an apkication where it mattered
Make a same type of vdo on 220v to 24v smps for long life time and most efficient
Hii👍
How fitting finding this video, as I am just about to build a few small regulators for use in theater props and got too lazy searching for the components myself ;)
You teach at a good pace, easy to understand. Good visual also.
Oh no, we have a problem on drc! I know, let's relax the rules. *Runs drc* - no errors! Problem solved 😎
With respect to LED's: given they are Light Emitting ->Diodes
I love this channel, thank you for existing!
I just got the notification and watched! Video came out a week ago. Wow youtube notifications are slow! This video was great! Thanks!
A 7805 in a PCB without space for a heatsink it's pretty useless
i am a beginner..
i want to know whether what you said means that he did it the wrong way and shouldnt have used that ic without heatsink?
Nope. Heat sink not needed for small currents and lower input voltages.
@@kennmossman8701 Current less than 500 mA and input voltages less than 7.5 volts.

Coming from Audio Engineering a Voltage Regulator is a Hard Limiter

How hard of a limiter? Semi, half mast, or full mast?

Depends if you did any online searches on the device(s) you are signed into CZcams with...cookies and search history give a lot of weight to what is advertised to you depending on your ad choices preferences and CZcams ad preferences.
Would be less likely to happen if you ask for ads to not be personalised and if you aren’t signed in to CZcams on the device you perform online searches with.
@@Infiniti25 oh, i forgot to state that i'm already subscribed a long time and follow every video. it really was a very crazy coincidence
This happens to me all the time,i think about a subject and i will see it on CZcams 😮
In awe and amazement...
Although I'm still in the model A technology...
I understood everything you said and am blown away at the computer designing.
That's like SR71 advancements to me.
🚲↗️🚗↗️🚀........↗️
Wow, this is very thorough! It's gotta be like about 1000 individual steps or so and buttons to push and stuff to do on a computer, to actually build this whole design from nothing, and since I'm not able to comprehend computer stuff and/or how or why they do what all they do, I was honestly completely lost as soon as you started doing stuff on the computer screen instead of on that breadboard, however IF I actually wanted to build this exact thing myself, it looks like I could just watch this entire video again from the 6 minute mark, (after getting a computer AND having someone help me download the software), and then just watch EACH individual step for a few seconds, then pause the video after each step and then do exactly that same thing on the computer, until I finally did ALL of the steps in this video and this project was completely done, which is kinda cool when you think about having that level of detail in a CZcams video!... If I was to do it that way then this whole project would probably take me (only) at least a few weeks to do exactly like this myself, but that's still WAY faster than I would take to build something like this completely by hand, which I know would be many months for sure!...
I just wish I personally knew a friend or somebody who had this exact kind of setup and could show me first hand, step by step, how to do it, but unfortunately I don't have or even know anyone like that who could. Nobody I know who has a computer even cares about building electronic stuff from scratch, they all just go out and buy a pre-made device for whatever they need. So I am the only "electronics nerd" I know, I just don't understand computers at all, because they are way too complicated for me. The closest thing I ever get to operating a computer is my cellphone, (which I am watching this video on and writing this comment on, and is plenty complicated enough for me already, lol!), but everything else electronics-wise, I do and (try to) build totally by hand, old-school style, because that's the only way I've ever been able to understand. All of this newfound "computer" stuff certainly LOOKS cool to at least watch what amazing things that can be done on a CZcams video, and it seems like it might could even make building stuff much quicker vs. totally by hand, (maybe even easier also, (?), but ONLY IF you know exactly what buttons to push and in what order to push them on the computer itself), but all of that is way above my head unless I have someone else show me and help me every step of the way.
Or, you just download the free file, upload it to the pcb website and order the board to your house without having to learn to design it
@@EngineeringMindset Yeah, that's all much easier said than done for me. I already can design circuits like this on paper and with a pencil, and on a breadboard like you showed, so understanding and designing a relatively simple circuit like this, that's not the problem. My issue is that I really have NO CLUE how computers work, OR how to "download" software, and definitely not how to actually USE said software. I don't even own a computer, (as close as I get to that is my cellphone, which I saw this video on and I'm writing this comment and reply on), but any computer stuff beyond that is just way too complicated for me to understand! I'm totally "old-school", and I can work on things just fine with a hammer and a screwdriver, (or a soldering iron), but when it comes to using a computer and knowing exactly which buttons to push on it, and when to push said buttons and in what order to make it actually do something useful, I am totally lost! I honestly don't even know how to do ANYTHING on a computer, not even turn one on or off properly...
I'm already almost a senior though, so I doubt I'll ever really understand all of this modern computer stuff anyway, so unless I had someone else who already knew this exact thing and who did it themselves already could show me step by step, I'll have to just continue doing all of my electronic tinkering by hand in my garage workshop... But that's OK too I think, because at least I still (try) to fix things that break or wear out... Most people nowadays are just of the totally wasteful mindset of "Just throw it away and buy a new one!", and that kind of thinking really disgusts me, so at least I'm one who is still actually interested in how basic electronic and electrical stuff works. I don't personally know anyone else who even cares at all about how electronic/electrical stuff works, unfortunately. Everyone else I know, (including all of the younger kids I know), is just of the "throwaway society", which isn't too good for the future of the planet and future generations, in my opinion!
First 👍🏻
Well done

Nowadays, linear voltage regulator becoming obsolete, switch mode is present and future
Thanks man. Your videos are great. Thanks for explaining all of the small things aswell
Guys, this is the quality! Thank you very much
Charging a phone this way is disgustingly inefficient. You need to mention that a buck converter would have worked much better for this application.
Loved the video, but this should be titled "how to use a voltage regulator". This did nothing to explain how a voltage regulator functions and operates, mostly "it does this and here's how to use it" which is still valuable but a misleading title.
Yeah buddy i totally agree with you i thought he is gonna design a new one and build a prototype then test it and show us. This is also a great video apart from misleading title
Yeah, I thought he was gonna describe the internals of the IC, not how to connect an IC
Very straight forward thank you.
I've found the best tool to cut the leads on components are fingernail cutters.
This is a very nice channel. I hope many aspiring engineers watch these channel's videos.
I don't think putting a 7805 on a circuit board can really be called "designing a voltage regulator". You bought a voltage regulator and put some filter caps on it.... poorly chosen ones, badly laid out, and with no heatsink, which means you get maybe a third of the current that the 7805 can support. This is a bit like going out and buying a motherboard and CPU, putting them into a box, and claiming you've "designed" a computer.
I wanted to point out a few things wrong with this PCB. First off, those traces will not stand the current without a significant temperature rise. Unless you meant for the traces to act like fuses then I would increase the width. Next, the diode you use for reverse polarity protection doesn't have much better vf at the currents you were using. While you did (at least I think) purposely choose a diode with low leakage current the vf is the thing you want to focus on in this circuit and the diode doesn't have that great of a vf. And, why not just use a p-channel MOSFET for reverse polarity protection? Furthermore, having the capacitors right next to the regulator probably isn't good for them. If you can even reach current levels that generate a substantial amount of heat without the traces burning out. Please make a new video that teaches people good design ideas and not just use autorouter.
