LM317BT Product Details

LM317BT Description


The LM217 and 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.



LM317BT 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



LM317BT Applications


  • Switching applications

  • Power management

  • DC-AC Conversion

  • Industrial
