Design a Custom BoardAbout This Component
Low-dropout positive voltage regulator providing fixed 3.3V output at up to 1.0A with 1.2V maximum dropout at 800mA. Features ±1.0% output accuracy, 20V maximum input rating, and integrated current limiting and thermal shutdown protection. Suitable for point-of-load regulation, battery chargers, and switching power supply post-regulation 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.
