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.
