TL431LIAQDBZR

Overview

The TL431LIAQDBZR is a programmable shunt regulator from Texas Instruments, designed for automotive applications. It operates within a voltage range of 2.5 V to 36 V and features an initial accuracy of 1%. The device supports a maximum cathode current of 15 mA and functions across a temperature range of -40°C to +125°C. Packaged in SOT-23-3, it offers optimized reference current characteristics suitable for precision power management tasks.

Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
Programmable output voltage via external resistors
Optimized reference current for low-power efficiency

Applications

Automotive power supply regulation
Precision voltage referencing in control circuits
Battery management systems

Procurement Notes

Verify the complete part number including suffixes to ensure correct package and tolerance specifications. Confirm AEC-Q100 qualification status if automotive compliance is required. Check datasheet revisions for any pinout or electrical parameter updates before finalizing design integration.

Selection Notes

Select this component when automotive qualification and high precision are required. Compare against standard TL431 variants if industrial grade suffices. Ensure the 15 mA cathode current meets load requirements. Verify thermal performance within the specified operating temperature range for the target application environment.

Part Context

This device belongs to the TL431LI-Q1 family of programmable shunt regulators. It shares functional similarities with other TL431 series parts but is specifically optimized for automotive environments. The LI variant denotes specific accuracy and current optimization compared to standard commercial grades.

Replacement Considerations

Direct substitutes include TL431AQDBZRQ1 for general automotive use or TL431LIBQDBZR for non-automotive precision needs. Verify pin compatibility and electrical parameters before substitution.
