LM117
LM217, LM317
1.2 V to 37 V adjustable voltage regulators
Features
Output voltage range: 1.2 to 37 V
Output current in excess of 1.5 A
0.1% Line and load regulation
Floating operation for high voltages
Complete series of protections: current limiting,
thermal shutdown and SOA control
Description
The LM117, LM217, LM317 are monolithic
integrated circuits in TO-220, TO-220FP, TO-3
and D²PAK packages intended for use as positive
adjustable voltage regulators.
They are designed to supply more than 1.5 A of
load current with an output voltage adjustable
over a 1.2 to 37 V 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.
