The three-pin SOT-23 footprint is common across many low-power references, so a pin-compatible replacement should fit the same board layout without a PCB spin.","metaTitle":"REF3112AIDBZRG4 series voltage reference, 1.25 V, ±0.2%","metaDescription":"Texas Instruments REF3112AIDBZRG4 series voltage reference, fixed 1.25 V output, ±0.2% tolerance, 20 ppm/°C drift, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±0.2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","Reference Type":"Series","Voltage - Input":"1.8V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"10 mA","Current - Supply":"135µA","Base Product Number":"REF3112","Noise - 0.1Hz to 10Hz":"17µVp-p","Noise - 10Hz to 10kHz":"24µVrms","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"20ppm/°C","Voltage - Output (Min/Fixed)":"1.25V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8300","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF3112AIDBZRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for REF3112AIDBZRG4?","answer":"Texas Instruments has not published an official successor for this part. For a pin-compatible alternative in the same SOT-23-3 footprint with a 1.25 V output, look at current-production series references from TI or other vendors — the REF3112 family shares the same base number, but verify the specific suffix for active status.
