LM217, LM317 1.2 V to 37 V adjustable voltage regulators Datasheet - production data Description The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP and DPAK packages intended for use as positive adjustable voltage regulators. They are designed to supply more than 1.5 A of load current with an output voltage adjustable over a 1.2 to 37 V range. The TO-220 TO-220FP nominal output voltage is selected by means of a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators. DPAK Features Output voltage range: 1.2 to 37 V Output current in excess of 1.5 A 0.1 % line and load regulation Floating operation for high voltages Complete series of protections: current limiting, thermal shutdown and SOA control Table 1.
