It delivers a stable reference voltage adjustable from 1.24 V up to 6 V, with a tight ±0.5% tolerance that holds across the -40°C to 85°C industrial temperature range. The shunt topology sinks current from a series resistor to ground, making it a simple, two-terminal device for generating a precision bias or threshold in power supplies, data converters, and supervisory circuits. No last-time-buy risk for new designs or ongoing production runs.","metaTitle":"TLV431BILPRE3 Shunt Voltage Reference, Adjustable 1.24V-6V","metaDescription":"TLV431BILPRE3 adjustable shunt reference, 1.24V to 6V output, ±0.5% tolerance, TO-92-3, -40°C to 85°C.

It is pin-compatible and functionally identical, but its maximum output voltage is 6 V versus the TL431's 36 V. Check that your circuit's reference voltage does not exceed 6 V before substituting."},{"question":"Is TLV431BILPRE3 RoHS compliant?","answer":"Yes, it is ROHS3 compliant."},{"question":"When sourcing TLV431BILPRE3, what's the closest functional second-source — LM4132AMF-4.1/NOPB?","answer":"The LM4132AMF-4.1/NOPB is a series reference, not a shunt reference — it requires a supply voltage above the output and delivers a fixed 4.096 V. The TLV431 is a shunt reference that sinks current from a resistor. They are not direct replacements; choose based on topology: shunt for two-terminal simplicity, series for lower quiescent current and tighter load regulation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLV431BILPRE3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLV431BILPRE3 when reusing this data.
