LM317: 1.2V to 37V Voltage Regulator
 
This device is a monlithic integrated circuit in TO-220, ISOWATT220™, TO-3 and D2PAK. It is designed to supply more than 1.5A of load current with an output volatge 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.
