Design a Custom BoardAbout This Component
Fixed low-dropout linear voltage regulator providing 1.2V output at up to 800mA. Features 1V typical dropout voltage, ±1% output accuracy at 25°C, and integrated current/thermal limiting. Requires only a 10µF stabilizing capacitor and is ideal for space-constrained applications requiring stable low-voltage rails.
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.
