Pack contains 10 regulators, LM317 ( LM317T ) 1.5 amp 1.2v to 37v adjustable positive voltage regulator in a TO-220 thru-hole package. Output voltage range: 1.2 to 37v output current in excess of 1.5AMP with complete series of protections: current limiting, thermal shutdown and SAO control.
The LM317 are monolithic integrated circuit in TO-220 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 other fixed regulators.
"A must have" in any electronics enthusiast tool box.
