LM117

LM117/LM217/LM317 1.2 V to 37 V adjustable voltage 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 Description The LM117/LM217/LM317 are monolithic integrated circuit in TO-220, TO-220FP, TO-3 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 only a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.
