The LM317 is a versatile adjustable three-terminal positive voltage regulator. It is designed to supply currents greater than 1.5 A over an output voltage range of 1.25 V to 37 V. This regulator requires only two external resistors to set the output voltage, simplifying circuit design.
Key features include internal short-circuit current limiting, thermal overload protection, and output safe-area compensation. These protections ensure reliable operation even under fault conditions. The device exhibits typical line regulation of 0.01% and load regulation of 0.1%.
The LM317 is available in multiple package types, including SOT-223, TO-220, and TO-263. These packages support both surface mount and through-hole mounting, offering flexibility for various PCB designs. The adjustable nature and robust protection mechanisms make the LM317 suitable for a wide array of applications.
