LM317 1.2V-37V Adjustable Voltage Regulator IC SMD (Pack of 5)

Sold By: HatchnHack

Min Qty:


The LM317 is a 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. 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.


  • 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


  • Power bank solutions
  • Motor Controls
  • Power Supply 
  • Desktop PCs
  • DIY Prototyping
