Design a Custom BoardAbout This Component
Precision shunt voltage reference IC providing a stable 3.0V output with ±0.5% initial accuracy tolerance. Features low output noise (35μVrms typical), wide operating current range of 60μA to 15mA, and low temperature coefficient of 100ppm/°C. Requires no external output capacitor and is suitable for data acquisition, field transmitters, and automotive applications requiring accurate voltage references.
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.
