AHK432
Adjustable Low Voltage Shunt Regulator
General Description
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
VREF (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.
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%.
