Design a Custom BoardAbout This Component
Adjustable linear voltage regulator with 100mA output current capability in SOT-89 surface-mount package. Provides stable positive output voltage from 1.25V to 37V with external resistor divider programming. Commonly used in low-power applications requiring adjustable DC supplies, battery charging circuits, and precision reference voltage generation.
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.
