LM317M, NCV317MA, NCV317M Voltage Regulator - Adjustable Output, Positive 500 mA The LM317M is an adjustable three−terminal positive voltage www.onsemi.com regulator capable of supplying in excess of 500 mA over an output voltage range of 1.2V to 37 V. This voltage regulator is exceptionally easy to use and requires only two external resistors to set the output Heatsink surface voltage. Further, it employs internal current limiting, thermal connected to Pin 2 shutdown and safe area compensation, making it essentially blow−out proof. The LM317M serves a wide variety of applications including local, on−card regulation. This device also makes an especially simple TO−220AB adjustable switching regulator, a programmable output regulator, or by T SUFFIX connecting a fixed resistor between the adjustment and output, the CASE 221AB LM317M can be used as a precision current regulator. 1 Features 2 3 • Output Current in Excess of 500 mA • Output Adjustable between 1.2 V and 37 V SOT−223 • Internal Thermal Overload Protection ST SUFFIX 1 • CASE 318E 2 Internal Short Circuit Current Limiting 3 • Output Transistor Safe−Area Compensation • Floating Operation for High Voltage Applications • 4 Eliminates Stocking Many Fixed Voltages DPAK • NCV Prefix for Automotive and Other Applications Requiring DT SUFFIX 1 2 Unique Site and Control Change Requirements; AEC−Q100 CASE 369C 3 Qualified and PPAP Capable • These are Pb−Free Devices Heatsink Surface (shown as terminal 4 in case outline drawing) is connected to Pin 2.
