Unlike a series reference, it sinks current through a cathode to the negative rail — the same topology as a Zener diode — so it operates from whatever supply is available, as long as the cathode current stays above 65 µA and below 12 mA. The 20 µVrms noise spec (10 Hz to 10 kHz) and 100 ppm/°C temperature coefficient make it suitable for precision analog chains — ADC references, comparator thresholds, or DAC bias — where a 1.225V rail is needed without a dedicated low-noise LDO. ## SC-70-5 — small footprint, but the cathode current sets the bias resistor The SC-70-5 package (also known as SOT-353) is a 5-lead surface-mount package about 2.0 mm × 2.1 mm — a tight fit for space-constrained boards. The shunt topology means the designer must size the series resistor from the supply to the cathode so that the cathode current stays between 65 µA (minimum to maintain regulation) and 12 mA (absolute maximum) across all load and supply conditions. Inventory that exists on the independent market is factory-original sealed reels or cut tape from genuine production runs — date-code spread varies by lot. For a pin-compatible replacement, the buyer should evaluate the broader LM4041 family (base product number LM4041) in the same SC-70-5 package and 1.225V fixed output with ±0.5% tolerance — the LM4041CIM7-1.2 or LM4041AIM7-1.2 may be available as active alternatives, though the exact tolerance and temperature range must be verified against the BOM requirement.","metaTitle":"LM4041CIM7X-1.2 Shunt Voltage Reference, 1.225V Fixed, ±0.5%","metaDescription":"LM4041CIM7X-1.2 precision shunt reference: 1.225V fixed output, ±0.5% tolerance, 65 µA cathode current, SC-70-5.","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); Cut Tape (CT)","Tolerance":"±0.5%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"65 µA","Base Product Number":"LM4041","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SC-70-5","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/26af4fd2ab0c421228a4f1c33eae6ec2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041CIM7X-1.2/alternatives.json"},"ai":{"faq":[{"question":"What is the cathode current for LM4041CIM7X-1.2?","answer":"The minimum cathode current required for regulation is 65 µA; the maximum continuous cathode current is 12 mA."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4041CIM7X-1.2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4041CIM7X-1.2 when reusing this data.
