Design a Custom BoardAbout This Component
Low-dropout positive voltage regulator delivering over 1.0 A output current with 1.2 V maximum dropout at 800 mA. Fixed 3.3 V output trimmed to ±1.0% accuracy, requires no minimum load, and operates from up to 20 V input. Includes current limiting, thermal shutdown, and safe operating area protection for consumer and industrial point-of-load 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.
