Design a Custom BoardAbout This Component
Ultra-low dropout linear voltage regulator providing fixed 5V output at 150mA with wide input range up to 40V. Features low quiescent current, thermal shutdown, and current limiting protection, making it ideal for USB-powered and battery-operated portable devices. RoHS compliant and available in space-saving SOT23 package.
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.
