NOT RECOMMENDED FOR NEW DESIGN USE AZ431L 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 (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 0.2Ω. Active output circuitry provides very sharp turn-on characteristics, making these devices excellent improved replacements for Zener diodes in many applications.
