Design a Custom BoardAbout This Component
Low-dropout linear regulator delivering 1.2A at 5V output with input range 2.5V to 18V. Features 350mV typical dropout at full current, high PSRR of 87dB at 120Hz, and integrated thermal/current protection. Suitable for SMPS post-regulation and point-of-load applications in consumer and industrial equipment.
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.
