Design a Custom BoardAbout This Component
Positive 1A low-dropout (LDO) linear voltage regulator with fixed 1.2V output. Delivers 1.5% output accuracy with typical 1.2V dropout at full current. Features integrated current limiting and thermal shutdown protection. Suitable for battery-powered systems, portable devices, and post-regulation applications.
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.
