Temperature drift is rated at 75 ppm/°C. ## Noise floor and output drive — sizing the reference for your load Low-frequency noise is specified at 33 µVp-p (0.1 Hz to 10 Hz) and 94 µVrms (10 Hz to 10 kHz). For a 3 V full-scale ADC, 33 µVp-p corresponds to roughly 0.001% of full scale — well below the quantization noise of a 12-bit converter (0.024% of FS). The wideband noise matters more if the reference feeds a high-speed pipeline ADC without a post-filter; a 0.1 µF bypass at the output pin knocks down the 10 kHz+ content. Output current is rated at 25 mA. That's enough to drive the reference input of several ADCs or a small resistive divider network without an external buffer. The 50 µA quiescent supply current keeps the part viable for battery-powered instruments — the REF3030 draws less than 0.2% of its output capability as overhead. ## Package and temperature grade — board-fit and environment The REF3030AIDBZT comes in a SOT-23-3 package (also listed as TO-236-3 / SC-59). Three pins — input, output, ground. Input voltage range is 3.05 V to 5.5 V, so the reference needs at least 50 mV of headroom above the 3 V output. No official second-source cross-reference is listed, but the base product number REF3030 shares the same die across multiple package and grade variants (AIDBZT is the SOT-23-3 tape-and-reel option).","metaTitle":"REF3030AIDBZT 3V Voltage Reference, ±0.2%, 75ppm/°C","metaDescription":"Texas Instruments REF3030AIDBZT series voltage reference: 3V fixed output, ±0.2% tolerance, 75ppm/°C drift, 33µVp-p noise, 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","Product Status":"Active","Reference Type":"Series","Voltage - Input":"3.05V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"25 mA","Current - Supply":"50µA","Base Product Number":"REF3030","Noise - 0.1Hz to 10Hz":"33µVp-p","Noise - 10Hz to 10kHz":"94µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"75ppm/°C","Voltage - Output (Min/Fixed)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF3030AIDBZT/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to REF3030AIDBZT?","answer":"Within the same REF3030 family, the REF3030AIDBZR is the same die and package but in a different reel quantity.
