LM117/217 LM317 1.2V TO 37V VOLTAGE REGULATOR s s s s s OUTPUT VOLTAGE RANGE : 1.2 TO 37V OUTPUT CURRENT IN EXCESS OF 1.5A 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, ISOWATT220, TO-3 and D2PAK 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.
