DESCRIPSION
The TL431Z is a three-terminal adjustable shunt regulator
with
temperature V
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℃.
