TLV431BQDBZRQ1

Overview

The TLV431BQDBZRQ1 is an automotive-grade, low-voltage adjustable precision shunt regulator from the TLV431B series. Manufactured by Texas Instruments, it operates within a voltage range of 1.24 V to 6 V with an initial accuracy of 0.5%. The device features a temperature coefficient of 161 ppm/°C and supports a maximum cathode current of 15 mA. It is qualified under AEC-Q100 standards for automotive applications and functions reliably across a temperature range of -40°C to +125°C.

Feature Summary

Automotive qualification compliant with AEC-Q100 standards
Adjustable output voltage capability within specified limits
High initial accuracy for precise reference control

Applications

Automotive power supply regulation
Precision voltage referencing in vehicle electronics
Low-voltage shunt regulation circuits

Procurement Notes

Verify the specific suffix QDBZRQ1 matches the required automotive grade and package configuration. Confirm AEC-Q100 compliance is necessary for the target application. Check datasheet revisions for any updates to electrical characteristics or pinout definitions before finalizing procurement specifications.

Selection Notes

Select this component when automotive reliability and low-voltage precision are required. Ensure the operating voltage stays within the 1.24 V to 6 V range. Consider the 15 mA current limit for load requirements. Verify thermal performance meets system constraints within the -40°C to +125°C operational window.

Part Context

This part belongs to the TLV431B family of adjustable shunt regulators designed for low-voltage applications. It serves as a drop-in replacement for standard TL431 devices in automotive contexts where higher reliability and lower voltage operation are prioritized over high-voltage capabilities found in other series variants.

Replacement Considerations

Direct substitutes include TLV431AIDBZRQ1 for non-automotive use or TLVH431BQDBZRQ1 for higher voltage ranges. Verify pin compatibility and electrical parameter alignment before substitution.
