AHK432

Adjustable Low Voltage Shunt Regulator

™

PowerManager

General Description

Features

The AHK432 is a low voltage adjustable shunt refer-

ence with thermal stability guaranteed over the full

industrial temperature range. This three-terminal

regulator has an output voltage range that extends

from V_REF(1.24V) to 20V, giving designers out-

standing flexibility in the development of power sup-

plies and instrumentation. With a low operating cur-

rent of 60µA, the AHK432 is well suited for battery-

powered portable electronic applications. It also has

a sharp turn-on characteristic and a dynamic resist-

ance of only 50mΩ, making it an excellent replace-

ment for zener diodes in low tempco designs.

•

Wide Output Voltage Range (1.24V to 20V)

Operating Current From 60µA to 100mA

Low Dynamic Output Resistance of 50mΩ

±0.5% Trimmed Voltage Reference

10mV (Typical) V_REFDeviation, From -40°C to

•

Surface Mount 3- or 5-Pin SOT23 or Through-

Hole 3-Pin TO-92 Package

Applications

The AHK432 is available in the Pb-free, surface-

mount 3- or 5-pin SOT23, as well as the through

hole TO-92. Three voltage tolerance options are

offered in each package: ±0.5%, ±1%, and ±2%.
