Design a Custom BoardAbout This Component
Precision shunt voltage reference providing a fixed 2.5V output with ±0.5% tolerance (C grade) and 100ppm/°C temperature coefficient. Operates across 45μA to 15mA with low output noise (35μVrms) and requires no external capacitors. Ideal for data acquisition systems, analog modules, and precision instrumentation requiring stable reference voltages over wide temperature ranges (-40°C to 125°C).
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.
