What a huge coincidence to have the same topic. When I've posted my video and saw your post too I couldn't believe it. The odds are low:))) Btw, very nice video 👌🏻

I had a 24 volt switched-mode power supply but needed 19 volts. To do this, I simply changed the voltage divider on the TL431. I connected a potentiometer (value corresponding to the old resistor that I removed) between the plus 24 volts and the 2.5 volt sense point of the TL431 and reduced the value until I could measure 19 volts at the output. Then I replaced it with a fixed resistor.

TechBuilder made a short facebook post on this a few months ago. Never knew how nifty it could be by adding an outboard pass transistor. Been using it as a handy adjustable voltage reference for adcs

This is the freakiest thing ever. Possibly. I’ve literally just been pricing up TL431s for the SMPS section of the Mac Classic analogue board (PSU and CRT section) schematic I’m staring at right now, when the notification for this video came through. Timing could not have been more perfect!

This video combines my two favourite things! A deep dive into a fun component and its applications, and a component that has become cheap because of how often it is used in industry. My last project actually used a TL431 - a voltage monitor to automatically cut-off power from a lead-acid battery for only a buck or two in parts. Thank you, and keep up the great videos!

Thank you for putting these EB videos together and sharing them! I really enjoy the "bite sized" info you give on a subject. You don't go into super detail, but give enough detail so that we can go off and find more details! I would love to hear your take on a deep dive into feedback theory and design. There is some much more to this subject that is not really common knowledge, so to speak. Ya know, I don't know what I don't know. 🤓

A very useful component, discovered it not too long ago when I tried building my first switched mode power supply, since it is so cheap and easy to get I use it in all sorts of applications from voltage references for arduino to tiny constant current load for my power supplies, amazing how versatile this little component is.

It's incredible how such a small component can be so useful. Amazing vid as always. Gonna buy myself some TL431's.

As new electronics thinker, I was going to order a whole kit of zener diode ....but after watching this video.....I will just buy some of these TL431. This is really good to know about this. Thank you #greatscott

My fav Op Amp was the 741, and was in a class with its designer as our instructor in 84. I like the way you present your evaluations Thanks

Working out how circuits work doesn't come easy for this old guy, so good explanations are a God send. Many thanks, have subscribed and hope to see more of your videos.

The TL431 has been used for decades. Introduced by TI in 1977, now made by many major semiconductor companies.

Ahhh yes voltage reference tl431 one of the most usefull components. As always awesome video🔥🔥🔥 Cheers!

Great Scott. If only you knew how much influence you had on me since i started watching your videos. Actually, i improved my veroboard skills by seeing how yo neatly arrange components in yours. You are my mentor. Thank you so much. 🙏🙏🙏

I AM SO GLAD WITH YOUR FREQUENCY OF VIDEOS LATELY! I know full well how much work this just be for you, but I think I speak for a great many of us, it really is exciting to see a new release from you! No matter the topic, you make it understandable, entertaining, engaging, and simply watchable for just about anybody. I think it is your super soothing cadence of speech, and that sweet, sweet German accent! 😁😁😁👏👏👍🏼👍🏼👍🏼😳😳😃😃😃

Please keep in mind one important characteristic of this programmable Zener IC. It's fully temperature compensated, unlike any Zener that ever lived. Zeners are so yesterday.

Just recently I was looking up the internet for over current pull down protection for my circuit and this IC popped up... Thanks for explaining the working in details!

I recently used the TL431 for balancing supercaps. Acts like a 2.5V Zener diode without any additional components, just REF to Cathode.

Yo Scott. Many thanks for the great tips and detailed explanations you always provide. I thoroughly enjoy watching your videos as the Electronics-bug got me, and your content along with ElectroNoobs... and I'm sure there's many more out there, really helps me ease in to the system without TOO many uncertainties. Safety precautions are at a high as I'm just getting started. Anyway, just thought I'd express my appreciation for the time, effort and energy you've put into your VERY WELL documented & Tested Content! Cheers mate!
