Design a Custom BoardAbout This Component
Precision adjustable shunt voltage reference IC with 1% accuracy in a 3-pin SOT-23 package. Provides a stable 1.24V internal reference that can be externally trimmed to higher voltages using resistor dividers. Commonly used in linear regulator feedback networks, battery chargers, and precision current-sense circuits requiring low-power operation.
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.
