ACE431S
Adjustable Precision Shunt Regulator
Description
The ACE431S 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 VREF
(approximately 2.5 V) to 18V with two external resistors. This device has a typical output impedance of
0.08Ω. Active output circuitry provides a very sharp turn on characteristic, making this device excellent
replacement for Zener diodes in many applications.
The ACE431S is characterized for operation from -40oC to 85oC, and five package options (SOT-23-3,
SOT-23-5, SOP-8, TO-92 and SOT-89-3) allow the designer the opportunity to select the proper package
for their applications.
