RC0431A (RC431A)  
Low-Voltage Adjustable Precision Shunt Regulator  
Features  
Description  
• Low voltage operation to 1.24V  
• 1% reference voltage tolerance  
• Output voltage adjustable from V to 12V  
ref  
• Low 80µA operational cathode current  
• 0.25typical output impedance  
• TO-92, SOT23-3 and SOT23-5 packages  
The RC0431A is a low-voltage 3-terminal adjustable  
precision voltage reference regulator. It has an excellent  
thermal stability over the standard commercial temperature  
range. The output voltage can be set to any value between  
Vref (1.24V) and 12V using two external resistors. The  
RC0431A operates from a lower voltage (1.24V) than the  
traditional shunt regulator references which operate from  
2.5V. When used with an optocoupler, the RC0431A will be  
an ideal voltage reference in an isolated feedback circuit for  
use in switched-mode power supplies and modular DC-DC  
converters. The RC0431A has a low output impedance of  
active output circuitry offering a very sharp turn-on  
characteristic. The RC0431A will be an excellent  
replacement for low-voltage zener diodes in many  
applications such as on-board regulation and adjustable  
power supplies.
