LM317M, NCV317MAB, NCV317MB 500 mA Adjustable Output, Positive Voltage Regulator The LM317M is an adjustable three-terminal positive voltage regulator capable of supplying in excess of 500 mA over an output http //onsemi.com http //onsemi.com voltage range of 1.2 V 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 SUFFI... See More ⇒
