Design a Custom BoardAbout This Component
Fixed 3.0V CMOS LDO regulator delivering 300mA with 65mV dropout voltage and extremely low 50µVrms noise. Features 70dB ripple rejection, ±2% output accuracy, and 60µA quiescent current. Ideal for battery-powered devices, portable electronics, and noise-sensitive applications requiring compact packaging.
Package: SOT-23-3 · 3 pins
Why does this need a breakout?
SOT-23's tiny 0.95mm pin pitch and compact form factor make hand-soldering tedious and prone to bridging errors. A breakout board breaks out the three pins to standard 0.1" spacing for breadboard prototyping, eliminating the need for specialized soldering equipment and enabling fast circuit iteration with transistors, diodes, and small-signal components.
