STMicroelectronics LM317B

LM317B; hic integrated circuits in TO-220, TO-22 0FP and D²PAK packages intended for us e as positive adjustable voltage regula tors. They are designed to supply more than 1.5 A of load current with an outp ut voltage adjustable over a 1.2 to 37 V range. The nominal output voltage is selected by means of a resistive divide r, making the device exceptionally easy to use and elimina.

Description
The LM217, LM317 are monolithic integrated circuits in TO-220, TO-220FP and
D²PAK 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.
