TL431AQDBVRG4

Overview

The TL431AQDBVRG4 is an adjustable precision shunt regulator from Texas Instruments, designed for automotive applications. It operates within a voltage range of 2.495V to 36V with an initial accuracy of 1%. The device supports a maximum cathode current of 100mA and withstands input voltages up to 37V. It features a temperature coefficient of 92ppm/°C and functions reliably between -40°C and 125°C. Packaged in a SOT-23 format, it serves as a high-performance reference voltage source.

Feature Summary

Automotive-grade qualification ensuring reliability in vehicle environments
Adjustable output voltage capability for flexible circuit design
High precision with 1% initial accuracy for stable reference performance

Applications

Automotive power supply regulation circuits
Precision voltage reference sources in harsh environments
Battery management system monitoring

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free status as per manufacturer standards. Confirm automotive grade AEC-Q100 qualification requirements match your application needs. Ensure the SOT-23 package dimensions align with your PCB footprint constraints. Check for any recent Product Change Notifications regarding assembly sites or marking changes.

Selection Notes

Select this component when automotive reliability and high precision are required. The 1% accuracy suits applications demanding tight voltage tolerances. Consider the SOT-23 package size for space-constrained designs. Verify that the 100mA current limit meets the load requirements of your specific shunt regulator topology.

Part Context

This part belongs to the TL431 family of adjustable shunt regulators. The 'Q' designation typically signifies automotive quality, while 'G4' denotes Green/RoHS-compliant packaging. It shares functional similarities with standard TL431 variants but offers enhanced durability for automotive use cases.

Replacement Considerations

Direct substitutes include TL431AQDBVR and TL431AQDBVT. Cross-manufacturer alternatives like AS431BKTR-G1 may offer similar electrical characteristics but require verification of automotive qualification status.
