1.2 V to 37 V adjustable voltage regulators
■ 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
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.
