ST8R00WPUR ST Power Management IC | 8-DFN(4x4) | 3A Step-Down Converter, 2.5V-5.5V Input

Product Overview

The ST8R00WPUR is a high-efficiency, monolithic synchronous step-down (buck) regulator from STMicroelectronics. It operates from an input voltage range of 2.5V to 5.5V, making it ideal for low-voltage power rails in portable and embedded systems. The device delivers up to 3A continuous output current with excellent load and line regulation. Housed in a compact 8-DFN (4x4mm) package, it offers a small footprint for space-constrained applications.
