General Description

Features

The AHK432 is a low voltage adjustable shunt refer-

ence with thermal stability guaranteed over the full

industrial temperature range. This 3-terminal regula-

tor has an output voltage range that extends from

V_REF(1.24V) to 20V, giving designers outstanding

flexibility in the development of power supplies and

instrumentation. With a low operating current of

60µA, the AHK432 is well suited for battery-powered

portable electronic applications. It also has a sharp

turn-on characteristic and a dynamic resistance of

only 50mW making it an excellent replacement for

zener diodes in low tempco designs.
