TL431 Power Constant Current Source Demo 1 

Very good video, as always. I really like the cable management, with the wires zip tied around the capacitor.

Thank you sir for teaching us about beginner electronic circuits 😊

Merci, i will try it.

👍👍👍👍👍👍

Nice story, but complex. You could take a look at the l 200 regulator. Greetings pe1krx

I will appreciate very much if you explain us the function of TL431 in wich the cathode is connected to the ground of 7805 regulator and the reference voltage is conected to a volage divider between 7805 output and ground ; so the 7805 output can deliver between 1 to 5 volts by changing the value of the voltage divider ,This circuir appears in the Forrest Mims Engineer's Notebook Thnak you very much
