ZHCSH33Z September 1997 – April 2025 LM317
PRODUCTION DATA
The LM317 is an adjustable three-pin, positive-voltage regulator capable of supplying up to 1.5A over an output voltage range of 1.25V to 37V. The device 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%. The LM317 includes current limiting, thermal overload protection, and safe operating area protection. Overload protection remains functional even if the ADJUST pin is disconnected.
The LM317 is designed to minimize the IADJUST current and make this current constant with line and load changes. A 100μA current from the ADJUST pin represents an error term.
