LM431SA/LM431SB/LM431SC

Programmable Shunt Regulator

Features

Description

• Programmable Output Voltage to 36 Volts

• Low Dynamic Output Impedance 0.2Ω Typical

• Sink Current Capability of 1.0 to 100mA

• Equivalent Full-Range Temperature Coefficient of

50ppm/°C Typical

• Temperature Compensated for Operation Over Full Rated

Operating Temperature Range

• Low Output Noise Voltage

The LM431SA/LM431SB/LM431SC are three terminal

output adjustable regulators with thermal stability over

operating temperature range. The output voltage can be set

any value between V

REF

(approximately 2.5 volts) and 36

volts with two external resistors. These devices have a

typical dynamic output impedance of 0.2Ω. Active output

circuit provides a sharp turn-on characteristic, making these

devices excellent replacement for Zener Diodes in many

applications.

• Fast Turn-on Response
