TL431
The TL431 is three-terminal adjustable shunt regulator
with specified termal stability.
The output voltage may be set to any value between
V REF (Approx. 2.5V) and 36V with two external resistors.
This device has a typical output inpedance of 0.2Ω.
Active output circuitry provides a very sharp turn-on
characteristic, making this device excellent
replacement for zener diodes in many application.
