LM317B - 1.2V TO 37V VOLTAGE REGULATOR

Download the LM317B datasheet PDF. This datasheet also covers the LM317 variant, as both devices belong to the same 1.2v to 37v voltage regulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP and D²PAK packages intended for use as positive adjustable voltage regulators.

They are designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 to 37 V range.

Key Features

  • Output voltage range: 1.2 to 37 V.
  • Output current in excess of 1.5 A.
  • 0.1% line and load regulation.
  • Floating operation for high voltages.
  • Complete series of protections: current limiting, thermal shutdown and SOA control.

LM217, LM317 Datasheet 1.2 V to 37 V adjustable voltage regulators TO-220 TO-220FP D²PAK Features • Output voltage range: 1.2 to 37 V • Output current in excess of 1.5 A • 0.1% line and load regulation • Floating operation for high voltages • Complete series of protections: current limiting, thermal shutdown and SOA control Description The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP and D²PAK packages intended for use as positive adjustable voltage regulators. They are designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 to 37 V range. The nominal output voltage is selected by means of a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.
