LM317

3-Terminal Adjustable Regulator

Datasheet Download


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. Also, the LM117 is packaged in

standard transistor packages which are easily mounted and handled.

In addition to higher performance than fixed regulators, the LM117 series offers full overload protection available only in

IC’s. Included on the chip are current limit, thermal overload protection and safe area protection. All overload protection

circuitry remains fully functional even if the adjustment terminal is disconnected.
