Design a Custom BoardAbout This Component
Precision adjustable shunt regulator with programmable output voltage from 1.24V to 16V and ±1.0% accuracy at 25°C. Features low dynamic impedance of 0.20Ω and operating current range of 50µA to 20mA. Ideal for precision voltage references, power supply feedback control, voltage monitoring, and zener diode replacement in analog and digital circuits.
Package: SOT-23-3 · 3 pins
Why does this need a breakout?
SOT-23's tiny 0.95mm pin pitch and compact form factor make hand-soldering tedious and prone to bridging errors. A breakout board breaks out the three pins to standard 0.1" spacing for breadboard prototyping, eliminating the need for specialized soldering equipment and enabling fast circuit iteration with transistors, diodes, and small-signal components.
