LM317M: Linear Voltage Regulator, Positive, Adjustable Output, 500 mA
The LM317M is an adjustable three-terminal positive linear voltage regulator capable of supplying in excess of 500 mA over an output voltage range of 1.2 V to 37 V. This linear 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. The LM317M serves a wide variety of applications including local, on-card regulation. This linear voltage regulator also makes an especially simple adjustable switching regulator, a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM317M can be used as a precision current regulator.
