LM431 - Programmable Shunt Regulator

Description

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 VREF (approximately 2.5 volts) and 36 volts with two external resistors.

Features

  • Programmable Output Voltage to 36 Volts Low Dynamic Output Impedance 0.20 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.
  • Fast Turn-on Response.
