LM317 Pinouts Datasheet


The LM317 device is an adjustable three-terminal positive-voltage regulator capable of supplying more than 1.5 A over an output-voltage range of 1.25 V to 37 V. It requires only two external resistors to set the output voltage. The device features a typical line regulation of 0.01% and typical load regulation of 0.1%. It includes current limiting, thermal overload protection, and safe operating area protection. Overload protection remains functional even if the ADJUST terminal is disconnected.


1. Output Voltage Range Adjustable From 1.25 V to 37 V
2. Output Current Greater Than 1.5 A
3. Internal Short-Circuit Current Limiting
