ADJUSTABLE PRECISION  
ZENER SHUNT REGULATOR  
Issue 1 - NOVEMBER 1998  
ZR431L  
DEVICE DESCRIPTION  
FEATURES  
The ZR431L is a three terminal adjustable  
shunt regulator offering excellent  
temperature stability and output current  
handling capability up to 25mA. The output  
voltage may be set to any chosen voltage  
between 1.24 and 10 volts by selection of  
two external divider resistors.  
Surface mount SOT23 package  
TO92 package  
2.5% and 1% tolerance  
Maximum temperature coefficient 50  
ppm/°C  
Temperature compensated for  
operation over the full temperature  
range  
The devices can be used as a replacement  
for zener diodes in many applications  
requiring an improvement in zener  
performance.  
Programmable output voltage  
100µA to 25mA current sink capability  
Low output noise  
The ZR431L is particularly used in the  
feedback control loop of switch mode power  
supplies. In this application the device 1.24  
volt reference enables the generation of low  
voltage supplies, typically 3.3 volts or 3volts.  
APPLICATIONS  
Shunt regulator  
Series regulator  
Voltage monitor  
Over voltage/ under voltage protection  
Switch mode power supplies
