Design a Custom BoardAbout This Component
Fixed low-dropout linear voltage regulator delivering 3.3V at up to 800mA output current in a DPAK surface-mount package. Features 1V typical dropout voltage, ±1% output accuracy at 25°C, and integrated current/thermal limiting. Requires only a 10µF bypass capacitor for stability, making it ideal for powering microcontrollers, sensors, and embedded systems.
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.
