Design a Custom BoardAbout This Component
Fixed-output positive voltage regulator providing stable 9V regulation from input voltages up to 30V. Delivers maximum 100mA output current with integrated current-limiting and thermal shutdown protection. Requires minimal external components, making it ideal for low-power applications like sensor circuits, microcontroller supply, and general-purpose 9V rails.
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.
