LM317LDR2G – ON-SEMI

The LM317LDR2G, manufactured by ON Semiconductor, is a precision adjustable three-terminal positive voltage regulator integrated circuit, supplied in an 8-SOIC surface-mount package. This linear regulator provides an output voltage adjustable from 1.2V to approximately 37V, with a typical output current capability of 100mA. Internal current limiting and thermal overload protection are incorporated to enhance device robustness and prevent damage under fault conditions. The device features a typical line regulation of 0.01%/V and load regulation of 0.1%/mA. The LM317LDR2G requires only two external resistors to set the output voltage, offering design flexibility. It is commonly used in applications requiring a stable, adjustable voltage source, such as power supplies, battery chargers, and instrumentation. The operating junction temperature range is typically -40°C to +125°C.
