Overview
The LM317MDT is an adjustable three-terminal positive voltage regulator produced by onsemi. It is capable of supplying in excess of 500 mA over an output voltage range of 1.2 V to 37 V. This regulator is exceptionally easy to use, requiring only two external resistors to set the output voltage. It features internal current limiting, thermal shutdown, and safe area compensation, making it essentially blow-out proof. The LM317MDT is available in a 3-pin DPAK package, which includes two tabs for easy mounting and integration.
