you ONLY ONE from all youtubers what i've seen, who right described how is TL431 works !!!!!! thank you!!!!

[@HaseebElectronics]

it is my pleasure and special thanks for your valuable words for my efforts

[@roseelectronics4582]

True! This explanation is the best so far from what I've watched too. Haseeb is a gem?!

Thank you for taking the time to explain this. I have a question though, when testing, the led still glows dimly before 2.5v is reached. I don't see a solid turn on at 2.5v. The led just gradually gets brighter as the voltage is increased. Is this correct?

[@HaseebElectronics]

in the same video i explained detailed process to test TL431

[@littlegeniusplayschool459]

Please explain about overdrive voltage of tl431. How much excess than 2.5 voltage can be safely applied to it

[@gorekBoy]

Hello. I'm testing TL431. My supply voltage is 12V and current limiting resistor is 1k. Both resistors in voltage divider is 10k so I suspect 5V on the output but instead I can see ~3,5V. Is it mean my TL431 is damaged? When I connect ref pin to cathode I have 2,5V.

[@g.shivapratheek7368]

I need low battery indicator when voltage come to 2.5v ledu want's to be on and when it was above 2.5v led should be off can you share one video for that

[@tvbox8478]

👍 ✋

[@HaseebElectronics]

thanks a lot

[@user-rk3od8fk8n]

Thik

[@carlodevinventiis1737]

Mr Haseeb,as always a very informative content.Keep doing.I would like to ask if in smps power supply with 5v output which use Tl431 is possibile to reduce voltage to 1.5 v working with resistors in the divider.If yes ,would help to teach us how and the interaction between tl431 and driver circuit.Tkx in advance Carlo

[@newmonengineering]

Thr tl431 will not operate below 2.5v so without some sort of trickery the answer is no. You could maybe find an alternative part that works with 1v or less that works the same way and then you could do this. But normally this is used to control the feedback to set the voltage and this part needs 2.5v before it operate. So 1.5 is too low to make it work like this.

[@newmonengineering]

The other problem is this normally drives an opto coupler and that has a minimum on voltage as well. It's minimum is probably too high to work at 1.5v

[@carlodevinventiis1737]

@@newmonengineering tkx a lot for the hint.I'm really interested to undersrand the limit in such feedback and drive circuits

[@raoamarjeet5473]

Sir what is difference between pnp transtor and this tl431

[@saruthapa2732]

but when I increase the voltage higher then 2.5v led turns off again. I want led off only lower then 2.5v but led stay on higher voltage. is there any way to do so? Thanks
