Design a Custom BoardAbout This Component
Low-noise LDO voltage regulator with 500mA output capacity and 1.2V fixed output. Features 340mV low dropout, 90µA quiescent current, and 40µV output noise. Includes reverse battery protection, thermal shutdown, and logic-compatible enable pin. Ideal for battery-powered portable equipment and post-regulation applications.
Package: SOT-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.
