Design a Custom BoardAbout This Component
Programmable shunt voltage reference IC with adjustable output from 2.495V to 36V. Sinks 1-100mA with 0.2Ω typical dynamic impedance and 2.495V internal reference. Commonly used for voltage regulation, power supply feedback circuits, and precision voltage setting applications requiring low impedance operation across industrial temperature ranges.
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.
