The 50 ppm/°C drift means the output shifts roughly 0.125 mV over a 25°C ambient swing — well within the LSB budget of a 12-bit ADC with a 2.5 V reference, but worth calculating for a 16-bit system aiming at 15 µV/LSB. ## SOT-23-3 footprint and shunt topology Housed in a standard SOT-23-3 (TO-236-3 / SC-59) surface-mount package, the part mates with a three-pin footprint — anode, cathode, and no-connect — and requires no output capacitor for stability, though a 0.1 µF bypass at the load side is typical practice. As a shunt reference, the LM4050AIM3-2.5+ sinks current through an external series resistor; the 65 µA minimum cathode current ensures the internal bandgap is biased correctly even at zero load.","metaTitle":"Analog Devices LM4050AIM3-2.5+ Shunt VREF, 2.5V ±0.1%","metaDescription":"Precision 2.5V shunt voltage reference in SOT-23-3. ±0.1% tolerance, 50ppm/°C drift, 15 mA output.
