Product details

Adjustable shunt reference — 1.24 V to 6 V, TO-92-3

It covers an output range from 1.24 V minimum up to 6 V maximum, set by two external resistors. Initial tolerance is ±1% — a standard precision grade for general-purpose regulation in power supplies, bias circuits, and monitoring thresholds. The shunt architecture sinks current through the cathode to ground, regulating the reference node voltage.

Low minimum operating current — 80 µA cathode current

The TLV431ACLP regulates with a minimum cathode current of 80 µA. This low floor suits battery-powered and low-quiescent-current designs where every microamp matters — the reference does not waste headroom in the bias chain. Maximum output current is 15 mA, which sets the upper bound for the cathode resistor and the load the reference can drive directly. For higher current needs, the TLV431 drives an external pass transistor.

Not specified for industrial or automotive extended-temperature environments.

Frequently asked questions

Can TLV431ACLP replace the TL431?

The TLV431ACLP is a lower-voltage variant of the TL431 family. The TO-92 pinout is similar, but the reference voltage and maximum ratings differ — confirm the circuit's voltage requirements before substituting.
