The low thermal mass means it reaches reflow temperature quickly — no risk of lifting a pad if the profile is reasonable.","metaTitle":"REF3125AIDBZRG4 2.5V Voltage Reference, ±0.2%, SOT-23-3","metaDescription":"Texas Instruments REF3125AIDBZRG4 series voltage reference, fixed 2.5V output, ±0.2% tolerance, 20ppm/°C drift, -40°C to 125°C, 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)","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":"2.55V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"10 mA","Current - Supply":"135µA","Base Product Number":"REF3125","Noise - 0.1Hz to 10Hz":"33µVp-p","Noise - 10Hz to 10kHz":"48µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"20ppm/°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/REF3125AIDBZRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the REF3125AIDBZRG4 tolerance?","answer":"The initial output voltage tolerance is ±0.2% at 25°C."},{"question":"Can REF3125AIDBZRG4 replace REF3125AIDBZT?","answer":"The REF3125AIDBZT is the same die in a different reel/tube packaging variant. The electrical specs — 2.5 V output, ±0.2% tolerance, 20 ppm/°C drift — are identical. The 'RG4' suffix indicates Tape & Reel packaging; the 'T' suffix typically indicates a smaller reel or tube.
