Product overview
Description
The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP, D²PAK and SOT223 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 a resistive divider, making the device exceptionally easy to use and eliminating the stocking of many fixed regulators.
