Design a Custom BoardAbout This Component
Low-dropout linear regulator for high-voltage applications up to 30V input. Delivers 3.3V at 100mA output with ±3% precision and minimal 0.1V typical dropout voltage. Ultra-low quiescent current of 2-3µA makes it ideal for battery-powered and portable equipment including communications, audio/video, and security systems.
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.
