It draws only 50µA supply current and can source or sink 25 mA, making it a low-power precision anchor for ADC reference, DAC bias, or regulator feedback in battery-operated and industrial designs. ## Noise and temperature drift — the precision story Low-frequency noise is specified at 14µVp-p over 0.1 Hz to 10 Hz, and 42µVrms over 10 Hz to 10 kHz — clean enough for a 12-bit ADC without external filtering. For a 1.25V reference, that drift is within the ±0.2% tolerance band across temperature. ## Package and supply — SOT-23-3 fit Housed in a 3-pin SOT-23-3 (also listed as TO-236-3, SC-59), this part is surface-mount and rework-friendly — the small body and exposed pad make hand reflow or hot-air removal straightforward if you keep the tip at 350°C and work the edges. Input voltage range is 1.8V to 5.5V, so it runs from a single Li-ion cell or a 3.3V / 5V rail without a separate supply.","metaTitle":"REF3012AIDBZTG4 Voltage Reference, 1.25V Fixed, ±0.2%","metaDescription":"Texas Instruments REF3012AIDBZTG4 series voltage reference, fixed 1.25V output, ±0.2% tolerance, 50µA supply current, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±0.2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Reference Type":"Series","Voltage - Input":"1.8V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"25 mA","Current - Supply":"50µA","Base Product Number":"REF3012","Noise - 0.1Hz to 10Hz":"14µVp-p","Noise - 10Hz to 10kHz":"42µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"75ppm/°C","Voltage - Output (Min/Fixed)":"1.25V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.5700","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF3012AIDBZTG4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF3012AIDBZTG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF3012AIDBZTG4 when reusing this data.
