ADJUSTABLE PRECISION SHUNT  
REGULATOR  
Features  
Description  
Precision reference voltage  
AP431A : 2.495V ± 0.5%  
The AP431A are 3-terminal adjustable precision  
shunt regulators with guaranteed temperature  
stability over the applicable extended commercial  
Sink current capability: 200mA  
Minimum cathode current for regulation: 300μA  
Equivalent full-range temp coefficient: 30 ppm/oC  
Fast turn-on response  
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,  
Low dynamic output impedance: 0.2Ω  
Programmable output voltage to 36V  
Low output noise.

Packages: TO-92,SOT-23, SOT-25 and SOP-8  
replacements for Zener diodes in many applications.  
The precise (+/-) 1% Reference voltage tolerance of  
the 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.
