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 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.
