Description
National Semiconductor LM317S Linear Voltage Regulator 1.2V to 37V 1.5A 0.5% SMT / SMD TO-263
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.
Features
- Output Voltage Range Adjustable
From 1.25 V to 37 V - Output Current Greater Than 1.5 A
- Internal Short-Circuit Current Limiting
- Thermal Overload Protection
- Output Safe-Area Compensation
The LM317 is a popular adjustable linear voltage regulator. It was designed by Robert C Dobkin in 1976 while he worked at National Semiconductor.
The LM337 (a negative complement to the LM317) regulates voltages below, rather than above, the reference. It was designed by Robert “Bob” Pease.
