That 10 mA output capability is enough to drive multiple ADC reference inputs or a small resistive divider chain without an external buffer — but the load regulation spec should be checked against the total current draw to keep the output within the ±0.05% window. ## Package and footprint for production The 8-VSSOP footprint is shared with other REF50xx family members, so a board layout can accommodate multiple output voltage options with a single copper pattern.","metaTitle":"REF5045IDGKR 4.5V Series Voltage Reference, ±0.05%, 3 ppm/°C","metaDescription":"Texas Instruments REF5045IDGKR precision series voltage reference: fixed 4.5V output, ±0.05% tolerance, 3 ppm/°C drift, 3 µVp-p noise.","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":"±0.05%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","Reference Type":"Series","Voltage - Input":"4.7V ~ 18V","lifecycle_stage":"eol_hot","Current - Output":"10 mA","Current - Supply":"1.2mA","Base Product Number":"REF5045","Noise - 0.1Hz to 10Hz":"3µVp-p","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"8-VSSOP","Temperature Coefficient":"3ppm/°C","Voltage - Output (Min/Fixed)":"4.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.2765","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF5045IDGKR/alternatives.json"},"ai":{"faq":[{"question":"Is REF5045IDGKR RoHS compliant and lead-free?","answer":"RoHS compliance and lead-free status are standard for TI's current-production REF50xx series.
