The STMicroelectronics LM217, LM317 Positive linear voltage regulator are robust as they feature internal current limiting and thermal shutdown. The adjustable voltage regulator is supplied in various packages from TO220, TO220FP and D2PAK devices. This series offers 1.5 Amps of load current with an output range of 1.2 V to 37 V by using the resistive divider.

0.1% line and load regulation
Safe operational area protection
Floating operation for high voltage

The STMicroelectronics LM317 are monolithic integrated circuit in TO-220, TO-220FP and D²PAK packages intended for use as positive adjustable voltage regulator. 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 regulator.
