General Description
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 50m
, making it an excellent replace-
ment for zener diodes in low tempco designs.
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%.
