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 (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 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
