It is designed for applications requiring a stable voltage reference in a small footprint — the SC-70-5 package (also known as SOT-353) occupies minimal board area and is suited for portable, battery-powered, and space-constrained designs. The shunt topology means it behaves like a two-terminal Zener diode: a series resistor sets the bias current from the supply, and the reference regulates the voltage across itself. ## 150 ppm/°C drift — the tempco budget The temperature coefficient of 150 ppm/°C means the output voltage can shift by up to 0.15 mV per degree Celsius. For a 12-bit ADC with a 2.5 V reference, that drift contributes roughly 0.75 LSB of error — acceptable for general-purpose measurement but worth noting for high-accuracy data acquisition. ## 12 mA output, 70 µA cathode — current budget The reference can source up to 12 mA of output current, which is enough to bias a single ADC reference input or a comparator threshold divider. The minimum cathode current is 70 µA — the series resistor must be chosen so that the total current through the reference (load current plus quiescent) stays above this floor to maintain regulation. A typical design with a 5 V supply and 1 mA load uses a 3.3 kΩ series resistor.","metaTitle":"LM4041DIM7X-1.2/NOPB Shunt Voltage Reference, 1.225 V ±1%","metaDescription":"Texas Instruments LM4041DIM7X-1.2/NOPB precision shunt reference, 1.225 V fixed output, ±1% tolerance, 150 ppm/°C drift, SC-70-5 package.","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":"±1%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"70 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":"150ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d2855eaed3a119e1ade8ae46dfbd1dff.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041DIM7X-1.2%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM4041DIM7X-1.2/NOPB obsolete or EOL?","answer":"No."},{"question":"What is the equivalent or cross reference for LM4041DIM7X-1.2/NOPB?","answer":"For a pin-compatible alternative within the LM4041 family, consider the LM4041AIM7X-1.2/NOPB (higher ±0.1% tolerance) or LM4041CIM7X-1.2/NOPB (±0.5% tolerance), both in the same SC-70-5 package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4041DIM7X-1.2-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4041DIM7X-1.2-NOPB when reusing this data.
