LM317T(L) Wide VIN Adjustable Voltage Regulator SPICE Macro Model. The LM317 voltage regulator is exceptionally easy to use and requires only two external resistors to set the output voltage. Further, it employs internal current limiting, thermal shutdown and safe area compensation, making it essentially blow−out proof.
