ROHS3 compliance is confirmed — no RoHS exemption expiry risk for EU-market builds. 70 mA cathode current rating means this shunt reference can sink enough current to bias an optocoupler LED in a feedback loop or power a small load directly — most general-purpose shunt references top out at 20-30 mA. The 100 µA minimum cathode current (Imin) sets the floor for the bias resistor: with a 12V supply and 1.24V reference, the series resistor must pass at least 100 µA to keep the device in regulation, which translates to a maximum resistor value of roughly 107 kΩ. Through-hole TO-92-3 package — the same footprint as the classic TL431 in TO-92, so a board originally laid out for that part accepts the TLVH431BCLPE3 without a PCB spin, provided the tighter tolerance is acceptable. ## Sourcing and provenance As an Active Texas Instruments part, the TLVH431BCLPE3 is sourced through authorized distribution channels — date codes and lot traceability are maintained through the full chain, and the laser-etched marking on the TO-92 body can be cross-checked against TI's factory marking standards for authenticity verification.","metaTitle":"Texas Instruments TLVH431BCLPE3 Shunt Reference, ±0.5%","metaDescription":"Active-production TLVH431BCLPE3 adjustable shunt voltage reference, ±0.5% tolerance, 70 mA output, TO-92-3.

This means the output voltage stays within 6 mV of the target at the 1.24V minimum, versus 27 mV for the standard part — relevant for precision feedback loops in power supplies or data-acquisition bias circuits."},{"question":"Will TLVH431BCLPE3 drop into a board designed for TL431IDBVR?","answer":"The TLVH431BCLPE3 is a through-hole TO-92-3 part, while the TL431IDBVR is surface-mount SOT-23-5 — they are not pin-compatible or footprint-compatible. A board designed for the SOT-23 package would need a redesign to accept the TO-92. However, if the original design used a through-hole TL431 in TO-92, the TLVH431BCLPE3 is a direct drop-in replacement with tighter tolerance."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TLVH431BCLPE3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TLVH431BCLPE3 when reusing this data.
