The SC338(A) is an ultra low output voltage dual power supply controller designed to simplify power management for notebook PCs.
The SC338(A) dual linear FET controller provides two independent, user‑adjustable outputs ranging from 0.5 V to 3.3 V, powered from either a 5 V or 12 V rail. It includes tight voltage regulation, enable control, power‑good monitoring, under‑voltage protection, and soft‑start features, making it suitable for notebook PCs and simple dual‑supply applications.
The device is supplied in an MSOP‑10 surface‑mount package and complies with RoHS and WEEE directives. Detailed electrical characteristics, pin descriptions, and application guidelines are provided, along with typical performance graphs and dimension drawings.
