TL431QDBVTG4

Overview

The TL431QDBVTG4 is an automotive-grade adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a reference voltage range of 2.495V to 36V and supports a maximum cathode current of 100mA. The device features an initial accuracy of 2% and a maximum temperature coefficient of 92ppm/°C. It is housed in a surface-mount SOT-23 package with three pins and functions across a temperature range from -40°C to 125°C.

Feature Summary

Automotive-grade qualification for reliable operation in vehicle electronics environments
Adjustable output voltage capability spanning 2.495V to 36V for flexible circuit design
High precision performance with 2% initial accuracy and low temperature drift

Applications

Precision voltage references in automotive power supply circuits
On-board charger regulation systems
Battery management system monitoring
DC-DC converter feedback loops

Procurement Notes

Verify the component's automotive grade status and RoHS compliance through official datasheets before integration. Confirm that the SOT-23 package dimensions match the target PCB footprint. Ensure the supplier provides traceability documentation required for automotive manufacturing standards. Check for any specific handling instructions related to moisture sensitivity levels during storage and assembly processes.

Selection Notes

Select this component when automotive reliability and high precision are required in space-constrained designs. The SOT-23 package offers a compact solution for surface-mount applications. Consider the 2% accuracy and wide operating temperature range suitable for harsh automotive environments. Evaluate the 100mA current drive capability against the load requirements of the specific feedback network.

Part Context

This part belongs to the TL431 family of adjustable shunt regulators, widely used as voltage references and error amplifiers. The 'Q' designation indicates automotive qualification, while 'G4' typically denotes lead-free packaging compliant with environmental directives. It serves as a cost-effective alternative to discrete Zener diodes in regulation circuits.
