Design a Custom BoardAbout This Component
Low-dropout linear voltage regulator delivering fixed 3.3V output at up to 300mA with only 260mV dropout at full load. Features micropower operation with internal current limiting and thermal shutdown protection. Ideal for battery-powered consumer electronics, handheld instruments, and portable cameras requiring extended runtime.
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.
