Design a Custom BoardAbout This Component
Fixed positive voltage regulator delivering 3.3V at up to 100mA output current in 8-SOIC surface-mount package. Includes internal current limiting and thermal shutdown protection, requiring no external components. Suitable for local board-level power regulation, noise elimination, and on-card voltage distribution in consumer 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.
