AP432/AP432A

ADJUSTABLE PRECISION SHUNT REGULATOR

Description

The AP432 and AP432A are 3-terminal adjustable precision shunt

regulators with guaranteed stable temperature over the applicable

extended commercial temperature range. The output voltage may be

set at any level greater than 1.24V (V

REF

) up to 20V 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.

The precise +/- 1% reference voltage tolerance of the

AP432/AP432A make it possible in many applications to avoid the

use of a variable resistor, consequently saving cost and eliminating

drift and reliability problems associated with it.
