It draws only 6.75 µA from the supply while sourcing up to 4 mA to the load — a combination that makes it suitable for battery-powered sensor nodes and portable instrumentation where every microamp counts. The series topology means the load current comes from the input, not from a resistor divider — output stays at 3V even when the load varies, unlike a shunt reference. ## Noise floor and temperature drift for ADC reference duty For a 12-bit ADC with a 3V reference, the noise contribution from the reference alone stays well under 1 LSB — the ADC's own quantization noise will dominate. The 100 ppm/°C temperature coefficient means the output shifts about 0.3 mV over a 10°C change, which is roughly 0.4 LSB at 12 bits. Operating temperature range is -40°C to +85°C, covering industrial enclosures and outdoor equipment that sees seasonal swings.","metaTitle":"MAX6129BEUK30+T Analog Devices 3V Series Voltage Reference","metaDescription":"MAX6129BEUK30+T 3V fixed output series voltage reference from Analog Devices. ±1% tolerance, 6.75 µA supply current, SOT-23-5 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Reference Type":"Series","Voltage - Input":"3.2V ~ 12.6V","lifecycle_stage":"eol_hot","Current - Output":"4 mA","Current - Supply":"6.75µA","Noise - 0.1Hz to 10Hz":"50µVp-p","Noise - 10Hz to 10kHz":"161µVrms","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.76","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.76000","currency":"USD"},{"qty":10,"price":"$2.47600","currency":"USD"},{"qty":25,"price":"$2.34080","currency":"USD"},{"qty":100,"price":"$2.02860","currency":"USD"},{"qty":250,"price":"$1.92456","currency":"USD"},{"qty":500,"price":"$1.72690","currency":"USD"},{"qty":1000,"price":"$1.45642","currency":"USD"},{"qty":2500,"price":"$1.19988","currency":"USD"},{"qty":5000,"price":"$1.15544","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MAX6129BEUK30+T?","answer":"No pin-compatible alternative is listed in the available records.
