Output current is rated at 10 mA. Supply current drawn by the reference itself is 1.2 mA. ## Package and rework consideration The small body means low thermal mass — it reflows quickly under a hot-air station, and the exposed die pad (if present on the VSSOP variant) helps with thermal coupling to the board.","metaTitle":"REF5045IDGKT Voltage Reference, 4.5V ±0.05%, 3ppm/°C","metaDescription":"Texas Instruments REF5045IDGKT precision series voltage reference: 4.5V fixed output, ±0.05% tolerance, 3ppm/°C drift, 3µVp-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); Cut Tape (CT)","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":"$7.8000","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/REF5045IDGKT/alternatives.json"},"ai":{"faq":[{"question":"What is the accuracy tolerance of REF5045IDGKT?","answer":"Initial tolerance is ±0.05%."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/REF5045IDGKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/REF5045IDGKT when reusing this data.
