Product Summary

The LM317MDT is a adjustable 3-terminal positive voltage regulator. The LM317MDT is capable of supplying in excess of 1.5A over a 1.2V to 37V output range. It 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.
