Design a Custom BoardAbout This Component
Precision micropower shunt voltage reference with 3.0V fixed output and ±0.1% accuracy at 25°C. Requires no external capacitor and operates from 60μA to 15mA with low temperature coefficient of 100ppm/°C. Ideal for data acquisition, field transmitters, and automotive applications requiring stable voltage references in compact packages.
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.
