LM317 Datasheet 3-Terminal Adjustable Regulator

Manufacturer: National Semiconductor (now Texas Instruments)

General Description

The LM117 series of adjustable 3-terminal positive voltage regulators is capable of supplying in excess of 1.5A over a 1.2V to 37V output range.

They are exceptionally easy to use and require only two external resistors to set the output voltage.

Further, both line and load regulation are better than standard fixed regulators.
