Description for the LM317

The LM317 device is an adjustable three-terminal positive-voltage regulator capable ofsupplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It requires only twoexternal resistors to set the output voltage. The device features a typical line regulation of0.01% and typical load regulation of 0.1%. It includes current limiting, thermal overloadprotection, and safe operating area protection. Overload protection remains functional even if theADJUST terminal is disconnected.
