DESCRIPTION
The LM217M/LM317M are monolithic integrated
circuits in TO-220, DPAK, SOT-82 and SOT-194
packages intended for use as positive adjustable
voltage regulators.
They are designed to supply until 500 mA 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.
