Output voltage range: 1.2 to 37V
Output current in excess of 100 mA
Line regulation typ. 0.01%
Load regulation typ. 0.1%
Thermal overload protection
Short circuit protection
Output transition safe area compensation
Floating operation for high voltage applications
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.
TO-92
SO-8
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.
