Design a Custom BoardAbout This Component
Three-terminal positive linear voltage regulator providing fixed 9V output at up to 500mA. Features internal current limiting, thermal shutdown, and safe area protection for robust operation. Available in compact DPAK package suitable for on-card regulation in power supply and embedded applications.
Package: TO-252-2 · 3 pins
Why does this need a breakout?
This 3-pin SMD package is difficult to hand-solder due to tight pin spacing and thermal requirements typical of power switching applications. A breakout board breaks out each pin to standard headers, enabling reliable breadboard prototyping and reducing cold-joint risk during development without needing a reflow oven or hot air station.
