AS431  
ADJUSTABLE PRECISION SHUNT REGULATORS  
Description  
Pin Assignments  
The AS431 is a three-terminal adjustable shunt regulator with  
guaranteed thermal stability over a full operation range. It features  
sharp turn-on characteristics, low temperature coefficient and low  
output impedance, which make it ideal substitute for Zener diode in  
applications such as switching power supply, charger and other  
adjustable regulators.
