Design a Custom BoardAbout This Component
Fixed positive voltage regulator delivering up to 100 mA output current at 9V in a compact SOT-89-3 package. Features integrated thermal overload and short-circuit protection, requiring no external components for operation. Suitable for local on-card regulation, noise elimination, and low-power applications up to 100 mA.
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.
