LM217L LM317L LOW CURRENT 1.2V TO 37V ADJUSTABLE VOLTAGE REGULATOR . . . . . . . . OUTPUT VOLTAGE RANGE : 1.2 TO 37V OUTPUT CURRENT IN EXCESS OF 100 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 SO-8 DESCRIPTION The LM217L/LM317L are monolithic integrated circuit in SO-8 and TO-92 packages intended for use as positive adjustable voltage regulators. They are designed to supply until 100 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.
