DESCRIPTION
The LM117/LM217/LM317 are monolithic
integrated circuit in TO-220, ISOWATT220, TO-3
and D2PAK 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.
