Design a Custom BoardAbout This Component
Adjustable step-down switching regulator with integrated power switch, rated for 500mA output current. Operates from 4.5V to 40V input with low quiescent current and built-in current limiting. Widely used in battery-powered systems, industrial equipment, and 3.3V/5V rail generation requiring compact form factors.
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.
