Technology Description
Adjustable Precision Shunt Regulator
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.
Features ● Low voltage operation (2.
5V) ● Adjustable output voltage V0=VREF to 18V ● Wide operating current range 150μA to 80mA ● Low dynamic output impedance 0.
08Ω (Typ) ● Trimmed bandgap design up to +0.
5% ● ESD rating is 6KV (Per MIL-STD-883D) ● ROHS Compliant and 100% Lead (Pb)-Free Application
● ● ● ● ● ● Linear Regulators Adjustable Supplies Switching Power Supplies Battery Operated Computers Instrumentation Computer Disk Drives
