Product Summary

The LM317T is an adjustable 3-terminal positive voltage regulator. It is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. The LM317T is 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 LM317T is packaged in standard transistor packages which are easily mounted and handled.
