Design a Custom BoardAbout This Component
Precision micropower shunt voltage reference providing a stable 2.5V output with ±1% accuracy at +25°C. Operates across a wide current range of 60µA to 15mA with low temperature coefficient of 100ppm/°C maximum and minimal output noise. Ideal for battery-powered equipment, data acquisition systems, and portable instrumentation requiring compact, low-power 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.
