Product details

Active shunt reference with tight tolerance

Output voltage is adjustable from 1.24 V up to 6 V, set by two external resistors, with a 15 mA cathode current rating that drives the feedback node of a switching regulator or an error amplifier.

Parametric fit for the BOM line

The ±0.5% tolerance reduces worst-case error in the regulation setpoint. Minimum cathode current is 100 µA, which sets the bias resistor value for the shunt; the part operates down to that current without dropping out of regulation.

Frequently asked questions

What is the closest pin-compatible alternative to TLV431BIDBVRG4?

Within the TLV431 family, the standard-grade TLV431IDBVR (1% tolerance) is pin-compatible and shares the same SOT-23-5 footprint. The B-grade offers tighter regulation for precision loops.
