Design a Custom BoardAbout This Component
Precision voltage reference IC providing 3.3V output with ±0.15% initial accuracy and 30ppm/°C temperature drift. Features ultra-low 3.9μA supply current, 110mV dropout voltage, and ±5mA output capability in compact SOT-23-3 package. Ideal for portable electronics, data acquisition, and sensor applications requiring stable reference voltage with minimal power consumption.
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.
