Design a Custom BoardAbout This Component
Adjustable precision shunt voltage reference IC with 0.5% accuracy, operating from 1.24V to 36V. Features low temperature coefficient and high output impedance, making it ideal for regulator feedback networks, power supply monitoring, and precision voltage divider applications. SOT-23-3 package enables compact designs in battery chargers, LED drivers, and industrial control 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.
