3-Terminal 1.5Amp Adjustable Voltage Regulator Description
The Bay Linear LM317 are monolithic integrated circuit in TO- 220, TO-252, SOT-223 and D2PAK packages intended for use as positive adjustable voltage regulators. They are designed to supply more than 1.5A 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.
