Design a Custom BoardAbout This Component
Adjustable precision shunt regulator with programmable output voltage from 2.5V to 36V and 0.4% accuracy. Features low 20ppm/°C temperature coefficient, 1-100mA sink current capacity, and thermal stability across -40 to +125°C. Ideal for switching power supplies, chargers, and precision voltage reference 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.
