If the system needs better than ±5 mV at 2.5 V without trimming, this part holds that line out of the tube. ## 50 µA quiescent — the power budget spec that matters for always-on rails Supply current is 50 µA typical. For a reference that stays powered continuously — battery monitors, always-on sensor bias, supervisory circuits — that 50 µA is a fixed overhead on the system power budget. It draws less than the leakage of many low-dropout regulators at high temperature, so it is a clean fit for a low-power rail that cannot afford a milliampere-class reference. ## Industrial temperature range and SOT-23-3 footprint","metaTitle":"REF3025AIDBZT voltage reference, 2.5V ±0.2%, 50µA, SOT-23-3","metaDescription":"Texas Instruments REF3025AIDBZT series voltage reference: 2.5V fixed output, ±0.2% tolerance, 50µA supply current, SOT-23-3 package.","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","Product Status":"Active","Reference Type":"Series","Voltage - Input":"2.55V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"25 mA","Current - Supply":"50µA","Base Product Number":"REF3025","Noise - 0.1Hz to 10Hz":"28µVp-p","Noise - 10Hz to 10kHz":"80µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"75ppm/°C","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF3025AIDBZT/alternatives.json"},"ai":{"faq":[{"question":"Can the REF3025AIDBZT be used in a 3.3 V system?","answer":"Yes. The input voltage range is 2.55 V to 5.5 V, so a 3.3 V supply rail is well within the operating window. The 2.5 V output is below the supply by 0.8 V, which leaves enough headroom for the series pass transistor to regulate cleanly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF3025AIDBZT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF3025AIDBZT when reusing this data.
