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.
