ACE432N
Precision adjustable shunt voltage reference
Description
The ACE432N is low-voltage three-terminal adjustable voltage references, with specified thermal
stability over applicable industrial and commercial temperature ranges. Output voltage can be set to any
value between VREF (1.24V) and 20V with two external resistors. These devices have a typical output
impedance of 0.25Ω. Active output circuitry provides a very sharp turn-on characteristic, making the
ACE432N excellent replacements for low-voltage Zener diodes in many applications, including onboard
regulation and adjustable power supplies.
