LM217L LM317L LOW CURRENT 1.2 TO 37V ADJUSTABLE VOLTAGE REGULATOR I I I I I I I I 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 TO-92 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 Figure 1: Schematic Diagram December 2005 Rev. 3 1/13 LM217L/LM317L Table 1: Absolute Maximum Ratings Symbol VI - VO Pd Topr Tstg Power Dissipation Operating Junction Temperature for LM217L Range for LM317L Storage Temperature Range Parameter Input-Output Differential Voltage Value 40 Internally Limited -40 to 125 0 to 125 -55 to 150 °C °C Unit V Figure 2: Pin Connection (top view) PIN 1 = ADJUST PIN 2 = IN PIN 3 = OUT BOTTOM VIEW SO-8 TO-92 Table 2: Order Codes TYPE LM217L LM317L SO-8 (TUBE) (*) LM217LD LM317LD TO-92 (BAG) (#) LM217LZ LM317LZ (*) Available in Tape & Reel with the suffix "-TR".
