1/11 February 2003 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 TRANSITION SAFE AREA COMPENSATION FLOATING OPERATION FOR HIGH VOLTAGE APPLICATIONS DESCRIPTION The LM217M/LM317M are monolithic integrated circuits in TO-220 and DPAK 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.
