Overview
The LM317MDT-001-ON, produced by onsemi, is an adjustable three-terminal positive linear voltage regulator. 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 known for its ease of use, requiring only two external resistors to set the output voltage. It incorporates internal current limiting, thermal shutdown, and safe area compensation, making it essentially blow-out proof.
