Design a Custom BoardAbout This Component
Positive adjustable linear voltage regulator capable of supplying up to 100mA output current. Features internal current limiting and thermal shutdown protection. Requires only two external resistors to set output voltage from 1.25V to 37V, making it ideal for custom power supply designs, lab equipment, and adjustable bias circuits.
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.
