Design a Custom BoardAbout This Component
Positive voltage regulator IC providing a fixed 12V output at up to 100mA from unregulated input supplies. Features internal current limiting and thermal shutdown protection, requiring minimal external components. Suitable for low-power applications needing regulated 12V supply, with input voltage range of 14-30VDC.
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.
