Design a Custom BoardAbout This Component
Precision micropower shunt voltage reference producing 2.5V output with ±0.2% initial accuracy. Operates across 60µA to 15mA with low 20ppm/°C temperature coefficient and 45µVRMS output noise. Ideal for battery-powered equipment, portable instruments, and data acquisition systems 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.
