Design a Custom BoardAbout This Component
Precision programmable shunt regulator with 1% initial tolerance, adjustable output voltage from 2.5V to 36V using external resistor divider. Features 0.2Ω output impedance, 1-100mA sink current capability, and stable operation from -40°C to 125°C. Commonly used in power supplies, voltage reference circuits, and as a superior Zener diode replacement.
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.
