Design a Custom BoardAbout This Component
Precision micropower shunt voltage reference producing a fixed 2.5V output with ±0.1% accuracy at 25°C. Features wide 60μA to 15mA operating current range, low 100ppm/°C temperature coefficient, and 35μVrms output noise. Requires no external capacitor and operates over industrial (-40°C to +85°C) or extended (-40°C to +125°C) temperature ranges. Ideal for data acquisition, analog modules, and automotive applications.
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.
