ON Semiconductor LM317/DLM317/NCV317 Voltage Regulator Datasheet
The document describes the LM317 family of adjustable 3-terminal positive voltage regulators capable of supplying in excess of 1.5 A over an output voltage range of 1.2 V to 37 V. These devices are designed for easy use, requiring only two external resistors to set the output voltage and featuring internal current limiting, thermal shutdown, and safe area compensation.
