TL431LIAEDBZRQ1

Overview

The TL431LIAEDBZRQ1 is an automotive-grade adjustable precision shunt voltage reference manufactured by Texas Instruments. It operates within a supply voltage range up to 36 V and provides an adjustable output voltage. The device features an initial accuracy of 1% and a temperature coefficient of 63 PPM/C. It supports a maximum shunt current of 15 mA with a minimum operating current of 600 uA. The component is housed in a SOT-23-3 surface-mount package and functions across a temperature range from -40°C to +150°C.

Feature Summary

Automotive qualification compliant for reliability in vehicle environments
Adjustable output voltage capability via external resistors
High thermal stability with low temperature coefficient
Precision shunt regulation topology for stable reference performance

Applications

Traction inverter design implementations
Voltage supervision circuits
Secondary side regulation in switch-mode power supplies

Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct automotive grade, tolerance, and packaging specifications. Confirm RoHS compliance status and functional safety FIT rate data relevant to your specific application requirements before finalizing procurement decisions.

Selection Notes

Select this component when automotive certification and high-temperature operation up to 150°C are required. The 1% initial accuracy and 63 PPM/C temperature coefficient suit applications needing moderate precision. Ensure the 15 mA maximum shunt current meets the circuit load requirements compared to higher current alternatives like the TL431B series.

Part Context

This device belongs to the TL431LI-Q1 family of programmable shunt regulators designed specifically for automotive electronics. It shares the core functionality of the standard TL431 but offers enhanced thermal performance and automotive reliability standards. The LI variant distinguishes itself through specific accuracy and temperature drift characteristics optimized for demanding vehicular power management systems.

Replacement Considerations

The TL431BIDBZRQ1 serves as a compatible alternative offering higher accuracy (0.5%) and current capacity (100 mA), though it has a lower maximum operating temperature of 125°C. Verify pinout compatibility and thermal limits when substituting.
