Design a Custom BoardAbout This Component
Low-dropout linear voltage regulator delivering up to 3A output current with fixed 3.3V output. Features 1.3V typical dropout at full load, ±1% output tolerance at 25°C, and integrated thermal protection. Suitable for battery-powered systems, embedded computing, and industrial applications requiring stable 3.3V rails with moderate to high current demands.
Package: TO-263-2 · 3 pins
Why does this need a breakout?
This SMD package requires a breakout board to interface with breadboards and standard prototyping layouts. The three-pin configuration with large copper pad underneath demands reflow soldering or careful hand-soldering to avoid cold joints, making a breakout board with standard 0.1" headers essential for reliable connections. Ideal for power regulators and MOSFETs where thermal performance and ease of iteration matter.
