TL431QDBVR

Overview

The TL431QDBVR is an adjustable shunt voltage reference IC manufactured by Texas Instruments, designed for automotive applications. It operates within a cathode voltage range of 2.495V to 36V and supports a maximum output current of 100mA. The device features an initial accuracy of ±2.2% and a maximum temperature coefficient of 92ppm/°C. It functions across an extended operating temperature range from -40°C to +125°C. Packaged in a surface-mount SOT-23-5 configuration with tape and reel delivery, it meets AEC-Q100 qualification standards.

Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
Adjustable output voltage capability spanning 2.495V to 36V
Extended industrial temperature operation from -40°C to +125°C

Applications

Automotive power supply regulation circuits
Precision voltage reference sources in vehicle electronics
Feedback control loops in DC-DC converters

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 automotive qualification status directly on the manufacturer datasheet. Ensure the SOT-23-5 package marking matches official specifications. Confirm RoHS compliance and REACH SVHC status through the latest environmental declaration provided by Texas Instruments prior to final procurement authorization.

Selection Notes

Select this component when automotive certification is mandatory for the target application. The ±2.2% accuracy suits general regulation tasks where higher precision variants are unnecessary. The wide operating current range accommodates various load conditions. Verify thermal management requirements align with the specified -40°C to +125°C operational envelope for robust performance.

Part Context

This part belongs to the TL431 family of three-terminal adjustable shunt regulators. Unlike standard commercial versions, the Q-series variant specifically targets automotive environments requiring enhanced reliability and temperature resilience. It serves as a foundational reference element in power management architectures, offering a cost-effective solution for voltage monitoring and control in demanding vehicular systems.
