The AP432/432A are 3-terminal adjustable precision shunt

regulators with guaranteed stable temperature over the

applicable extended commercial temperature range. The output

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

AP432/432A 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.
