Features
Description
The LM217L/LM317L are monolithic integrated
circuit in SO-8 and TO-92 packages intended for
use as positive adjustable voltage regulators.
They are designed to supply until 100 mA of load
current with an output voltage adjustable over a
1.2 to 37V range.
Order codes

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.
