As a shunt reference, it operates from any supply voltage above 1.225 V plus the headroom needed for the series resistor. A 3.3 V rail works fine as long as the resistor is chosen to maintain at least 80 µA cathode current at the maximum load."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4041B12IDCKR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4041B12IDCKR when reusing this data.
