USE AS431 AP431/AP431A ADJUSTABLE PRECISION SHUNT REGULATOR Description Pin Assignments 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 (VREF) 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. (1) SOT25 (2) SO-8 (Top View)

use of a variable resistor, consequently saving cost and eliminating
drift and reliability problems associated with it. CATHODE 1 REF 2 (5) SOT23 Precision Reference Voltage
