LP38500/2-ADJ, LP38500A/2A-ADJ 1.5A FlexCap Low Dropout Linear Regulator for 2.7V to 5.5V Inputs
The LP38500/2-ADJ is a 1.5 A FlexCap low‑dropout linear regulator that operates from a 2.7 V to 5.5 V input and provides an adjustable output from 0.6 V to 5 V. It features unique compensation allowing any type of output capacitor, low ground‑pin current (typically 2 mA) and a shutdown quiescent current of 25 nA.
The device is offered in TO‑263, TO‑263 THIN and LLP‑8 packages, includes protection features such as over‑temperature and over‑current shutdown, and is specified for operation from –40 °C to +125 °C. Detailed electrical characteristics, pin descriptions, ordering information and typical performance graphs are provided.
