Description

The ACE432 is a low voltage three terminal adjustable shunt regulator with a guaranteed thermal

stability over applicable temperature ranges. The output voltage can be set to any value between

The device has a typical output impedance of 0.30Ω. Active output circuitry provides a very sharp turn on

characteristic, making this device excellent replacement for Zener diodes in many applications.

The ACE432 is characterized for operation from 0℃ to 105℃, and two package options (SOT-23-3 and

TO-92) allow the designer the opportunity to select the proper package for their applications.
