DESCRIPTION
The LM117/LM217/LM317 are monolithic inte-
grated circuit in TO-220 and TO-3 packages in-
tended for use as positive adjustable voltage regu-
lators.
Theyaredesigned to supply morethan 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 excep-
tionally easy to use and eliminating the stocking of
many fixed regulators.
