Design a Custom BoardAbout This Component
Precision voltage reference IC with ±0.2% initial accuracy and 75ppm/°C temperature drift. Delivers up to 25mA output current with low quiescent current of 42µA typical. Operates across -40°C to +125°C industrial temperature range. Ideal for loop-powered field transmitters, sensor conditioning, and battery-powered instrumentation requiring stable precision 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.
