Design a Custom BoardAbout This Component
Low-noise CMOS LDO regulator delivering 3.3V at 300mA with 170mV dropout voltage in compact SOT-23-3 package. Features 60µV RMS output noise, 68dB ripple rejection at 1kHz, and 0.1µA standby current, making it ideal for battery-powered portable devices and low-power applications requiring clean regulated rails.
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.
