LM3411 Overview

Description

The LM3411 is a low power fixed-voltage (3.3V or 5.0V) precision shunt regulator designed specifically for driving an optoisolator to provide feedback isolation in a switching regulator. The LM3411 circuitry includes an internally compensated op amp, a bandgap reference, NPN output transistor, and voltage setting resistors.

Key Features

  • Custom voltages available (3V–17V)
  • Wide output current range, 20 µA–15 mA
  • Low temperature coefficient
  • Available in 5-lead SOT23-5 surface mount package (tape and reel)
