The AHK432 is a low voltage adjustable shunt reference
with thermal stability guaranteed over the full
industrial temperature range. This three-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 60μA, the AHK432 is well suited for batterypowered
portable electronic applications. It also has
a sharp turn-on characteristic and a dynamic resistance
of only 50mΩ, making it an excellent replacement
for zener diodes in low tempco designs.
The AHK432 is available in the Pb-free, surfacemount
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%.
