Design a Custom BoardAbout This Component
Precision voltage reference IC in compact SOT-23-3 package offering ±0.2% initial accuracy with 75ppm/°C temperature drift. Provides 25mA output current across selectable voltage options (1.25V to 4.096V) while consuming only 42µA quiescent current. Designed for industrial applications including field transmitters, solar systems, and battery-powered equipment operating from -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.
