LM431 Adjustable Precision Zener Shunt Regulator

September 2, 2010

LM431

Adjustable Precision Zener Shunt Regulator

General Description

The LM431 is a 3-terminal adjustable shunt regulator with

guaranteed temperature stability over the entire temperature

range of operation. The output voltage may be set at any level

greater than 2.5V (V

REF

) 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 excellent

replacement for many zener diode applications.

Features

■

Average temperature coefficient 50 ppm/°C

■

Temperature compensated for operation over the full

temperature range

■

Programmable output voltage

■

Fast turn-on response

■

Low output noise
