The output voltage can be set to any value between VREF )approximately 1.24V) to 8V with two external resistors. 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.
