LM3411

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.

Key Features

  • n Fixed voltages of 3.3V and 5.0V with initial tolerance of ± 1% for standard grade and ± 0.5% for A grade
  • 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)

Applications

  • Use with LDO regulator for high-precision fixed output regulators
