TLV431AQPK

Overview

The TLV431AQPK is an automotive-grade, low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 6 V and provides an adjustable output voltage from 1.24 V to 6 V. The device features a typical initial accuracy of ±1.5% and supports a maximum cathode current of 100 mA. Designed for robust performance in harsh environments, it functions reliably across an extended temperature range of -40°C to +125°C. The component is housed in a compact SOT-89-3 surface-mount package, ensuring suitability for space-constrained automotive applications requiring high reliability.

Feature Summary

Automotive-grade qualification compliant with AEC-Q100 standards for enhanced reliability
Low-voltage operation optimized for systems powered between 2.5 V and 6 V
Wide operating current range supporting cathode currents up to 100 mA
Precision adjustable reference with tight initial accuracy tolerance

Applications

Automotive power supply regulation circuits
Battery management system voltage monitoring
On-board charger (OBC) feedback loops
DC-DC converter output regulation

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 automotive qualification status before integration. Ensure the SOT-89-3 package variant matches the target PCB footprint design. Confirm that the selected supplier source provides traceability documentation required for automotive manufacturing quality standards.

Selection Notes

Select this component when automotive reliability is mandatory and input voltages remain below 6 V. It serves as a direct upgrade for standard TLV431 devices in safety-critical designs. Consider the 100 mA drive capability for driving optocouplers or transistor bases directly without additional buffering stages.

Part Context

This part belongs to the TLV431 family of low-voltage shunt regulators. The 'Q' suffix specifically denotes automotive grade qualification, distinguishing it from commercial variants like the TLV431AIPK. It shares functional similarities with the TLVH431 series but is optimized for lower voltage ranges compared to the higher voltage TL431 counterparts.
