TL431QDBVT

Overview

The TL431QDBVT is a three-terminal programmable shunt voltage reference manufactured by Texas Instruments. It operates within an output voltage range of 2.495V to 36V and supports a maximum cathode current of 100mA. The device features an initial accuracy tolerance of ±2.2% and functions across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-23-5 (SC-74A) surface-mount footprint, it serves as a precision adjustable regulator suitable for automotive and industrial applications requiring stable voltage references.

Feature Summary

Provides precise adjustable voltage regulation via external resistors
Designed for high thermal stability across extended temperature ranges
Offers low dynamic output impedance for effective noise rejection

Applications

Automotive power supply regulation systems
Portable equipment battery management circuits
DC-to-DC converter feedback loops

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q101 automotive qualification status before integration. Ensure the SOT-23-5 package dimensions align with the target PCB layout constraints. Confirm that the ±2.2% initial accuracy meets the system's voltage reference requirements without additional calibration.

Selection Notes

Select this component when automotive-grade reliability and wide operating temperatures are required. Compare against standard commercial grades if cost sensitivity outweighs the need for extended thermal performance. Verify that the 100mA current capability suffices for the intended load conditions.

Part Context

This part belongs to the TL431 family of programmable shunt regulators. It shares functional similarities with other TL43x variants but distinguishes itself through its qualified automotive grade designation and specific packaging configuration. It replaces older discrete zener diodes in precision control applications.

Replacement Considerations

Direct substitutes include other TL431 variants with compatible pinouts such as TL431ACDBVT or TL431IDBVT, provided their accuracy and temperature ratings meet the design specifications.
