LM317L 3-Terminal Adjustable Regulator General Description
The LM317L adjustable regulator provides a selectable output from 1.2 V to 37 V at up to 100 mA. It is offered in TO‑92, SO‑8, and 6‑Bump micro‑SMD packages and includes internal current limit, thermal overload, and safe‑area protection.
Typical applications include replacing fixed regulators, creating programmable output supplies, precision current sources, and simple switching regulators. The device operates from –25 °C to 125 °C and features high ripple rejection when the adjustment pin is bypassed.
