Design a Custom BoardAbout This Component
Fixed-output 1A low-dropout linear regulator providing 3.3V with typical 1.2V dropout at full load. Features 1.5% output accuracy, integrated current limiting, and thermal shutdown protection. Suitable for battery-powered systems, portable electronics, and post-regulation in switching supplies.
Package: SOT-223-3 · 3 pins
Why does this need a breakout?
SOT-223 three-pin regulators and transistors are difficult to hand-solder due to tight 1.5mm pitch and heat-sinking requirements. A breakout board brings standard 0.1" header spacing, eliminating soldering challenges and enabling immediate breadboard prototyping without rework or micro-soldering tools.
