LM317

Description

The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP, D²PAK and SOT223 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
