DESCRIPSION
The TL431Z 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 TL431Z is characterized for operation
from -40℃ to +125℃.
