AS432ECLPT Overview

1.24V Precision Adjustable Shunt Reference

SEMICONDUCTOR
1.24V Precision Adjustable Shunt Reference
Description
The AS432 is a three terminal adjustable shunt regulator utilizing an
accurate 1.24V bandgap reference. The AS432 is functionally similar to
an AS431 except for its lower reference voltage, making it usable in a
wide variety of low voltage applications.
Because of its robust bipolar technology, the AS432 handles a wide
range of current, and holds off more than 18V so its use is not limited to
low power, low voltage systems. Significant care has been taken to pro-
vide adequate AC bandwidth to allow the AS432 as an amplifier in con-
trol systems and power electronics.
