Design a Custom BoardAbout This Component
Fixed positive voltage regulator IC delivering 12V at up to 100mA output current. Features internal current limiting and thermal shutdown protection, requiring minimal external components for basic applications. Suitable for low-power supply circuits in consumer and industrial electronics where regulated 12V is needed.
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.
