Design a Custom BoardAbout This Component
Low-power precision voltage reference IC with ±0.15% initial accuracy and 30ppm/°C temperature drift. Delivers ±5mA output current with only 110mV dropout voltage and 3.9μA quiescent current. Ideal for portable equipment, data acquisition systems, and battery-powered applications requiring stable reference signals.
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.
