Design a Custom BoardAbout This Component
Fixed positive voltage regulator IC delivering regulated 5V output at up to 100mA load current. Features internal thermal shutdown and current limiting protection. Commonly used in battery-powered equipment, microcontroller circuits, and low-power analog applications requiring stable 5V supply from higher input voltages.
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.
