Design a Custom BoardAbout This Component
Low-noise LDO voltage regulator with 1.8V fixed output, 500mA capacity, and 340mV dropout voltage. Features 90μA quiescent current, 1% accuracy, and reverse battery protection. Ideal for battery-powered portable devices, instrumentation, and SMPS 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.
