1 / 11 page  LM117/217 LM317 1.2V TO 37V VOLTAGE REGULATOR November 1999 s OUTPUT VOLTAGE RANGE : 1.2 TO 37V s OUTPUT CURRENT IN EXCESS OF 1.5A s 0.1% LINE AND LOAD REGULATION s FLOATING OPERATION FOR HIGH VOLTAGES s COMPLETE SERIES OF PROTECTIONS : CURRENT LIMITING, THERMAL SHUTDOWN AND SOA CONTROL DESCRIPTION The LM117/LM217/LM317 are monolithic integrated circuit in TO-220, ISOWATT220, TO-3 and D 2PAK packages intended for use as positive adjustable voltage regulators. They are designed to supply more than 1.5A of load current with an output voltage adjustable over a 1.2 to 37V 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.
