AS432 Datasheet | Astec

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 provide adequate AC bandwidth to allow the AS432 as an amplifier in control systems and power electronics.
