Design a Custom BoardAbout This Component
Low-dropout linear regulator with 4.4V fixed output, 100mA maximum current, and 30V maximum input rating. Features ultra-low quiescent current (≤3μA), 100mV typical dropout voltage, and ±3% output accuracy. Suitable for battery-powered equipment, audio/video devices, and communication systems requiring high input voltage tolerance.
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.
