Design a Custom BoardAbout This Component
Low-dropout linear regulator delivering up to 300mA output current from 1.2V to 5.5V input supply. Features 2µA quiescent current, 0.15V dropout at 300mA, and integrated current limit and thermal protection. Ideal for battery-powered and ultra-low-power applications requiring minimal standby drain.
Package: TSOT-23-5 · 5 pins
Why does this need a breakout?
This 0.95 mm pitch SMD package is incompatible with breadboards and difficult to hand-solder. A breakout board brings the five pins to standard 0.1″ spacing, enabling rapid prototyping without reflow equipment. Essential for evaluating precision analog ICs like current-sense amplifiers in development circuits.
