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.

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

Package: TO-220
