Product details

Adjustable shunt reference for precision bias and monitoring

The Texas Instruments TLV431BILPRE3 is a low-voltage, adjustable precision shunt reference in a TO-92-3 through-hole package. It delivers a stable reference voltage adjustable from 1.24 V up to 6 V, with a tight ±0.5% tolerance that holds across the -40°C to 85°C industrial temperature range. The shunt topology sinks current from a series resistor to ground, making it a simple, two-terminal device for generating a precision bias or threshold in power supplies, data converters, and supervisory circuits.

No last-time-buy risk for new designs or ongoing production runs.

Frequently asked questions

Is TLV431BILPRE3 a direct replacement for TL431?

Yes, the TLV431 is a lower-voltage variant of the industry-standard TL431. It is pin-compatible and functionally identical, but its maximum output voltage is 6 V versus the TL431's 36 V. Check that your circuit's reference voltage does not exceed 6 V before substituting.

Is TLV431BILPRE3 RoHS compliant?

Yes, it is ROHS3 compliant.

When sourcing TLV431BILPRE3, what's the closest functional second-source — LM4132AMF-4.1/NOPB?

The LM4132AMF-4.1/NOPB is a series reference, not a shunt reference — it requires a supply voltage above the output and delivers a fixed 4.096 V. The TLV431 is a shunt reference that sinks current from a resistor. They are not direct replacements; choose based on topology: shunt for two-terminal simplicity, series for lower quiescent current and tighter load regulation.
