AS432

1.24V Precision Adjustable Shunt Reference/Amplifier

SEMICONDUCTOR

Features

Description

Temperature-compensated:

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.

50 ppm/¡C

0.25% to 2.0% bandgap offered

Internal amplifier with 150 mA

capability

Because of its robust bipolar technology, the AS432 handles a wide range of cur-

rent, and holds off more than 18V so its use is not limited to low power, low volt-

age systems. Significant care has been taken to provide adequate AC bandwidth

to allow the AS432 as an amplifier in control systems and power electronics.
