DESCRIPSION

The TL431 is a three-terminal adjustable shunt regulator

with specified thermal stability over applicable

temperature V_REF(Approx. 2.5V) and 40V with two

external resistors. This device has a typical dynamic

output impedance of 0.2Ω. Active output circuitry provides

a very sharp turn-on characteristic, making this device

excellent replacement for zener diodes in many

applications. The TL431 is characterized for operation

from -40℃ to +125℃.
