Design a Custom BoardAbout This Component
Ultra-low dropout (ULDO) linear voltage regulator delivering fixed 3.3V output at 150mA from input up to 40V. Features low quiescent current, 1V dropout at 100mA, high output accuracy, and integrated current limiting with thermal shutdown. Ideal for battery-powered and portable applications requiring efficient voltage regulation.
Package: SOT-89-3 · 3 pins
Why does this need a breakout?
SOT-89-3 is too small and has leads too close together to hand-solder reliably or plug into breadboards. A breakout board spaces the three pins to standard 0.1" pitch, making it compatible with solderless prototyping and eliminating the need for fine-pitch soldering skills. Essential for rapid development with voltage regulators, transistors, and other common three-terminal devices.
