LM431  
Adjustable Precision Zener Shunt Regulator  
General Description  
Features  
n Average temperature coefficient 50 ppm/˚C  
The LM431 is a 3-terminal adjustable shunt regulator with  
guaranteed temperature stability over the entire temperature  
range of operation. It is now available in a chip sized pack-  
age (4-Bump micro SMD) using National’s micro SMD pack-  
age technology. The output voltage may be set at any level  
greater than 2.5V (VREF) up to 36V merely by selecting two  
external resistors that act as a voltage divided network. Due  
to the sharp turn-on characteristics this device is an excel-  
lent replacement for many zener diode applications.  
n Temperature compensated for operation over the full  
temperature range  
n Programmable output voltage  
n Fast turn-on response  
n Low output noise  
n LM431 in micro SMD package  
n See AN-1112 for micro SMD considerations
