Design a Custom BoardAbout This Component
Fixed 12V linear voltage regulator IC rated for 100mA maximum output current in a compact SOT-89 surface-mount package. Features thermal overload protection and short circuit current limiting for safe operation. Suitable for low-power applications requiring regulated 12V supply from higher input voltages.
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.
