Product Information

LM217M LM317M MEDIUM CURRENT 1.2 TO 37V ADJUSTABLE VOLTAGE REGULATOR s s s s s s s s OUTPUT VOLTAGE RANGE : 1.2 TO 37V OUTPUT CURRENT IN EXCESS OF 500 mA LINE REGULATION TYP. 0.01% LOAD REGULATION TYP. 0.1% THERMAL OVERLOAD PROTECTION SHORT CIRCUIT PROTECTION OUTPUT TRANSISTOR SAFE AREA COMPENSATION FLOATING OPERATION FOR HIGH VOLTAGE APPLICATIONS TO-220 DESCRIPTION The LM217M/LM317M are monolithic integrated circuits in TO-220, DPAK, SOT-82 and SOT-194 packages intended for use as positive adjustable voltage regulators. They are designed to supply until 500 mA 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.
