AP431/AP431A

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 may be

set at any level greater than 2.495V (V

REF

) 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 Zener diodes in many

applications.
