Product details

Its ±0.5% tolerance means you can set a reference voltage between 1.24 V and 6 V without external trimming for most precision rails — think ADC references, comparator thresholds, or regulated supply feedback dividers. The 15 mA cathode current rating handles the shunt path for typical low-power loads, and the 100 µA minimum cathode current keeps it biased cleanly even in micropower designs.

Industrial temp range and package fit

The SOT-23-5 package is a standard footprint; the SC-74A / SOT-753 case is the same 5-pin outline. Surface-mount rework is straightforward with hot air or a fine-tip iron — no lab bench needed, it swaps on site if you have the kit.

Active lifecycle — no end-of-life watch

For a production BOM this means you are not chasing a sunset part; it is a stable line-item for ongoing builds.

Frequently asked questions

Is TLV431BQDBVRE4 a drop-in replacement for TL431?

The TLV431BQDBVRE4 is a lower-voltage variant of the TL431 family — it shares the same shunt-reference topology and SOT-23-5 footprint, but its output range tops out at 6 V versus the TL431's 36 V. For designs needing a reference below 6 V, it is a functional drop-in; for higher output voltages, stay with the TL431.

What is the TLV431BQDBVRE4 accuracy and tolerance?

The TLV431BQDBVRE4 has a ±0.5% tolerance on the reference voltage. That is tight enough for a 12-bit ADC reference or a precision comparator threshold without external trim.
