DESCRIPTION
The AIC431/TL431A/TL431 are 3-terminal ad-
justable precision shunt regulators with guar-
anteed temperature stability over the applica-
ble extended commercial temperature range.
The output voltage may be set at any level
greater than 2.495V (V
REF
) up to 30V merely
by selecting two external resistors that act as
a voltage divider network. These devices have
a typical output impedance of 0.08
. Active
output circuitry provides a very sharp turn-on
characteristics, making these devices excel-
lent improved replacements for zener diodes
in many applications.
The precise
±
0.5% reference voltage toler-
ance of the AIC431 makes it possible in
many applications to avoid the use of a vari-
able resistor, consequently saving cost and
eliminating drift and reliability problems asso-
ciated with it.
