* Output Voltage Range : 1.2 TO 37V
* Output Current In Excess Of 1.5A.(0.5A for TO-39)
* 0.1% Line And Load Regulation Floating Operation For High Voltages
* Complete Series Of Protections: Current Limiting, Thermal Shutdown And SOA Control
The LM317 is monolithic integrated circuit in TO-220, ISOWATT220, TO-39 and TO-3 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.
