Design a Custom BoardAbout This Component
Low-dropout linear voltage regulator providing fixed 5V output at up to 100mA from inputs up to 60V. Features automotive-grade load dump protection (60V), reverse battery protection, thermal shutdown, and internal current limiting. Ideal for battery-powered equipment requiring minimal dropout voltage and low quiescent current.
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.
