Product details

Shunt reference for precision bias rails

The shunt architecture means it sinks current through the cathode to regulate the output voltage, with a minimum cathode current of 100 µA and a maximum output current of 15 mA.

The ±0.5% tolerance is a BOM-fit differentiator: it tightens the reference accuracy over the standard 1% TLV431 grade, reducing the worst-case voltage error in ADC reference or comparator threshold circuits. The adjustable output spans 1.24 V (the internal bandgap) up to 6 V, set by two external resistors in the classic shunt configuration. For a 3.3 V rail, the feedback divider ratio lands near 1.66:1, well within the cathode current compliance.

The SOT-23-5 footprint is shared with the broader TLV431 family, so a drop-in replacement for the standard-grade version is straightforward if tolerance requirements relax.

Frequently asked questions

What is the tolerance of TLV431BIDBVTE4?

The TLV431BIDBVTE4 has a ±0.5% initial tolerance, tighter than the standard 1% grade.

Is TLV431BIDBVTE4 pin compatible with TL431?

The TLV431BIDBVTE4 uses the same SOT-23-5 pinout as the standard TL431 in that package, so it is a direct footprint replacement. The key difference is the lower minimum cathode current (100 µA vs 1 mA for the TL431), which matters for low-power designs where the bias current budget is tight.

What is the minimum cathode current for TLV431BIDBVTE4?

The minimum cathode current is 100 µA, significantly lower than the 1 mA typical for the standard TL431, enabling use in micropower bias circuits.

How does TLV431BIDBVTE4 compare to TL431?

The TLV431BIDBVTE4 is a low-voltage variant of the TL431 family. It operates from a 1.24 V reference (vs 2.5 V for TL431) and requires only 100 µA cathode current (vs 1 mA). The ±0.5% tolerance is tighter than the standard 1% TL431 grade. Both use the same SOT-23-5 footprint.
