AP432/AP432A

ADJUSTABLE PRECISION SHUNT REGULATOR

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 VREF up to 20V merely by selecting two external resistors that act as a voltage divider network. These devices have a typical output impedance of 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.
