Design a Custom BoardAbout This Component
The L5973D is a monolithic step-down switching regulator with 2.5A internal switch capable of delivering >2A DC output current. Operating from 4V to 36V input, it provides adjustable output from 1.235V to 35V at 250kHz fixed frequency with ±2% reference accuracy. Features include low dropout operation, internal current limiting, thermal shutdown, and synchronization capability, making it suitable for consumer electronics, networking, computing, and industrial applications.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
