2.5V Low-Voltage Adjustable

Precision Shunt Regulator

NIKO-SEM

L431

GENERAL DESCRIPTION

FEATURES

The L431 is a three-terminal adjustable shunt

regulator utilizing an accurate 2.5V band-gap

reference. The output voltage can be set to any

value between 2.5V (V_REF) to 29V with two

external resistors as shown in the typical

application circuit. The device exhibit a wide

operating current range of 0.4 to 100 mA with a

typical dynamic impedance of 0.25Ω. The cha-

racteristics of these reference make it exce-

llent replacements for zener diodes in many

applications such as digital voltmeters, power

supplies, and op amp circuitry. The 2.5V volt

reference makes it convenient to obtain a

stable reference from 5.0V logic supplies.

The L431 shunt regulator is available in three

voltage tolerances (0.5%, 1.0% and 2%) and

three package options (TO-92, SOT-23-3,

SOT-23-5 and SOIC-8).

z Internal amplifier with 70 mA capability
