Fixed 1.25 V reference in a SOT-23-3
The MAX6101EUR+T is a series voltage reference from Analog Devices that delivers a fixed 1.25 V output with ±0.4% initial tolerance. It runs from a 2.5 V to 12.6 V input rail and draws 125 µA quiescent supply current — low enough for battery-powered bias circuits. The output is rated for 5 mA, enough to bias a handful of op-amp inputs or an ADC reference pin, but not for powering downstream loads. The SOT-23-3 package (TO-236-3 / SC-59 compatible) keeps board area small, and the -40°C to +85°C temperature grade covers industrial and outdoor telecom environments.
