Product details

Adjustable shunt reference in SOT-23-3

It regulates an output voltage set by two external resistors anywhere between its 1.24 V minimum and 6 V maximum. The ±1% tolerance on the reference voltage makes it a tighter-grade alternative to the standard TL431's ±2% bin — useful when the feedback divider in a power supply or the threshold in a comparator needs better than 2% accuracy without trimming. The part sinks up to 15 mA and requires only 80 µA of cathode current to maintain regulation. That low minimum bias is the key spec for battery-powered or low-quiescent designs: the reference itself does not eat the current budget. The SOT-23-3 package fits tight layouts and shares a common footprint with the industry-standard TL431 in SOT-23, so a board designed for the TL431AIDBZR accepts this part without a layout change.

Frequently asked questions

Can TLV431AIDBZRG4 be used as a TL431 replacement?

It depends on the circuit. The TLV431 operates at a lower reference voltage (1.24 V vs 2.495 V) and a lower minimum cathode current (80 µA vs 1 mA). In a circuit designed for the TL431, the feedback divider must be recalculated for the 1.24 V reference. The pinout in SOT-23 is the same, so the physical swap is possible, but the output voltage will shift unless the resistor values are changed.
