Precision 3 V reference in a SOT-23-3
The Maxim Integrated MAX6063AEUR+T is a series voltage reference delivering a fixed 3 V output with ±0.2% initial tolerance and a 20ppm/°C temperature coefficient. It operates from a 3.2 V to 12.6 V input rail and supplies up to 5 mA to the load. Housed in a SOT-23-3 package, this reference targets precision analog circuits — ADC/DAC bias, sensor excitation, and regulator feedback — where output accuracy and low drift matter more than raw output current.
The SOT-23-3 footprint (also listed as TO-236-3 / SC-59) is a common three-pin surface-mount layout, making it a drop-in for existing reference sockets on mixed-signal PCBs.
