DESCRIPTION

The

LM117/LM217/LM317

are

monolithic

integrated circuit in TO-220, ISOWATT220, TO-3

and D

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.
