Product details

Adjustable shunt reference with ±0.5% tolerance

It provides a stable reference voltage adjustable from 1.24 V up to 6 V, with a tight ±0.5% tolerance that suits precision bias, comparator threshold, and regulator feedback applications. The shunt architecture means it sinks current from the load side, requiring only a cathode current of 100 µA minimum to regulate.

Housed in a 5-pin SOT-23-5 (SC-74A) surface-mount package. Standard reflow profile for MSL 1 or 2 applies; check the reel label for moisture sensitivity. The SOT-23-5 layout is common, so a second-source footprint is straightforward.

For BOM continuity, the active status means no near-term obsolescence risk.

Frequently asked questions

What is the difference between TLV431BQDBVT and TL431?

The TLV431BQDBVT is a lower-voltage variant of the classic TL431, with a minimum reference voltage of 1.24 V versus the TL431's 2.5 V. It also offers a tighter ±0.5% tolerance compared to the standard TL431's typical ±1% or ±2% grades. Pin-compatible in the same SOT-23-5 footprint, so a drop-in swap is possible if the circuit's reference voltage requirement is below 2.5 V.
