IRU431L/IRU431AL

LOW -VOLTAGE ADJUSTABLE

PRECISION SHUNT REGULATOR

PRELIMINARY DATASHEET

FEATURES

DESCRIPTION

SOT23-5 package

The IRU431L is a three-terminal adjustable shunt regu-

lator that can also be used as a precision voltage refer-

ence. Its output voltage may be set to any value be-

tween Vref(1.24V) and 6V with two external resistors as

shown in the typical application circuit. Other applica-

tions of this device include the use as a merged ampli-

fier and reference in applications such as a linear regu-

lator or as the secondary side controller in low voltage

power supply applications. The IRU431L only requires

80mA maximum quiescent current before regulating, mak-

ing it ideal as a voltage reference for battery type appli-

cations.
