AP431/AP431A  
ADJUSTABLE PRECISION SHUNT REGULATOR  
Description  
Pin Assignments  
(1) SOT25  
(Top View)  
(2) SO-8  
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 0.2. 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  
AP431/AP431A 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.
