ACE432
Technology Precision adjustable shunt voltage reference
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
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.
Features
• Low voltage operation (1.24V)
• Adjustable output voltage VD=VREF to 8V
• Wide operating current range 60μA to 100mA
• Low dynamic output impedance 0.30Ω (Typ.)
• Trimmed bandgap design up ±0.5%
• ESD rating is 2.5KV (Per MIL-STD-883D)
Application
• Linear Regulators
• Adjustable Supplies
• Switching Power Supplies
• Battery Operated Computers
• Instrumentation
• Computer Disk Drives
