Description

The AHK432 is a low voltage adjustable shunt reference with thermal stability guaranteed over the full industrial temperature range. This 3-terminal regulator has an output voltage range that extends from VREF (1.24V) to 20V, giving designers outstanding flexibility in the development of power supplies and instrumentation. With a low operating current of 60A, 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.

The AHK432 is available in the surface-mount 3 or 5 pin SOT-23, as well as the through hole TO-92.Three voltage tolerance options are offered in each package: ±0.5%, ±1%, and ±2%.
