The SPX2975 is a low dropout linear regulator with integrated PNP pass transistor. It provides 5V fixed output with input voltage range from 4.5V to 5V, and output current up to 400mA.
The SPX2975 is a low‑dropout linear regulator designed for automotive and industrial systems. It provides a fixed 5 V output at up to 400 mA, features very low quiescent current (60 nA), short‑circuit protection, programmable safety timer and 4 kV ESD protection. The device includes an integrated reset circuit that monitors the output voltage and generates a reset signal when the voltage falls below a programmable threshold.
Typical applications include automotive electronics, wireless stations and industrial control. The regulator is offered in 5‑pin TO‑220, TO‑263 and TO‑252 packages, with lead‑free options available. Ordering information and part numbers are provided for tape‑and‑reel and bulk packaging.
