Design a Custom BoardAbout This Component
Three-terminal positive linear voltage regulator delivering fixed 3.3V output at up to 100mA with internal current limiting and thermal shutdown protection. Requires no external components and features ±4% accuracy (A grade). Ideal for local on-card regulation, noise elimination, and as a Zener replacement with lower quiescent current.
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.
