The LM117, LM217, and LM317 are monolithic integrated circuits in TO-220, TO-220FP, TO-3 and D²PAK 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 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.
This document provides technical specifications for the LM117, LM217, and LM317 monolithic integrated circuits, which are positive adjustable voltage regulators available in TO-220, TO-220FP, TO-3, and D?PAK packages. The devices 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 using a resistive divider.
