Design a Custom BoardAbout This Component
Fixed negative voltage regulator delivering -5V at up to 100mA output current in a compact SOT-89-3 surface-mount package. Features internal current limiting and thermal shutdown protection, requiring no external components for basic operation. Suitable for local on-card regulation, noise elimination, and distributed power applications.
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.
