LM317L: Linear Voltage Regulator, Positive, Adjustable Output, 100 mA

The LM317L is an adjustable 3-terminal positive linear voltage regulator capable of supplying in excess of 100 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 them essentially blow-out proof. The LM317L serves a wide variety of applications including local, on card regulation. This linear voltage regulator can also be used to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the LM317L can be used as a precision current regulator.
