The maximum cathode current is 15 mA, which limits how many loads you can hang off the reference before it drops out of regulation. For a single ADC reference input drawing 1–2 mA, there is plenty of headroom; driving multiple converter channels or a resistive divider network will consume that budget quickly. ## TO-92-3 package and through-hole mounting The part comes in a TO-92-3 through-hole package. This is the classic three-lead transistor outline — hand-solderable, breadboard-friendly, and common in low-volume production.","metaTitle":"LM4040C50ILPE3 Shunt Voltage Reference, 5V ±0.5%, TO-92-3","metaDescription":"Texas Instruments LM4040C50ILPE3 precision shunt reference, fixed 5V output, ±0.5% tolerance, 100ppm/°C drift, -40°C to 85°C, TO-92-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Bulk","Tolerance":"±0.5%","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"95 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"80µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"TO-92-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5600","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040C50ILPE3/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4040C50ILPE3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4040C50ILPE3 when reusing this data.
