ADJUSTABLE PRECISION SHUNT REGULATOR
Description
The AP431 and AP431A are 3-
terminal adjustable precision shunt
regulators with guaranteed temperature stability over the applicable
extended commercial temperature range. The output voltage ma
y be
set at any level greater than 2.495V (VREF) up to 36V
merely by
selecting two external resistors that act as a voltage
divider network.
These devices have a typical output impedance of 0. 2Ω
. Active output
circuitry provides very sharp turn-on
characteristics, making these
devices excellent improved replacements for Z
ener diodes in many
applications.
The precise (+/-) 1% r
eference voltage tolerance of the
AP431/AP431A make it possible in
many applications to avoid the
use of a
variable resistor, consequently saving cost and eliminating
drift and reliabi l ity problem s ass ociated with it.
