Design a Custom BoardAbout This Component
Low-dropout linear regulator IC with 3V fixed output, 100mA maximum output current, and up to 30V input voltage tolerance. Features ultra-low quiescent current (≤3µA) and minimal dropout voltage (~0.1V typical), making it ideal for battery-powered and communication equipment requiring high-voltage input capability with tight voltage regulation (±3% accuracy).
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.
