Design a Custom BoardAbout This Component
Fixed-output linear voltage regulator delivering 9V at up to 1A output current in TO-252 (DPAK) surface-mount package. Features thermal overload and short-circuit protection with safe operating area (SOA) limiting. Suitable for general-purpose power supply applications requiring regulated 9V outputs.
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.
