APL431  
Adjustable Precision Shunt Regulator  
Features  
General Description  
The APL431 is a 3-terminal adjustable voltage refer-  
ence with specified thermal stability over applicable  
commercial temperature ranges. Output voltage may  
be set to any value between Vref (2.5 V) and 20 V with  
two external resistors (see Figure 2). When used  
with an photocoupler, the APL431 is an ideal voltage  
reference in isolated feedback circuits for 2.5V to 12V  
switching-mode power supplies. This device has a  
typical output impedance of 0.1. Active output cir-  
cuitry provides a very sharp turn-on characteristic,  
making the APL431 excellent replacements for ze-  
ner diodes in many applications, including on-board  
regulation and adjustable power supplies.  
Precise Reference Voltage to 2.500V  
Guaranteed 0.5%, 1% or 2% Reference
