TLVH431BQDBZT

Overview

The TLVH431BQDBZT is a low-voltage adjustable precision shunt regulator from Texas Instruments, designed for automotive and industrial applications. It operates within a supply voltage range of 2.5 V to 20 V, delivering an adjustable output voltage up to 18 V. The device features an initial accuracy of 0.5% and a temperature coefficient of 138 PPM/°C. It supports a maximum cathode current of 80 mA with a minimum operating current of 80 µA. Packaged in a compact SOT-23-3 surface-mount case, it functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
Low-voltage operation enabling compatibility with single-cell battery systems
High precision with 0.5% initial accuracy for stable reference performance

Applications

Battery management systems in electric vehicles
Precision voltage references in automotive instrumentation
Isolated feedback loops in DC-DC converters

Procurement Notes

Verify the specific suffix 'QDBZT' to confirm the component meets AEC-Q100 qualification requirements for automotive use. Ensure the ordering configuration matches the required tape-and-reel packaging format. Cross-reference the datasheet revision date to validate technical specifications against current manufacturing standards before finalizing procurement decisions.

Selection Notes

Select this component when high accuracy and automotive qualification are required in a small footprint. Compare the 80 mA cathode current capability against load requirements. Consider the SOT-23-3 package dimensions for PCB layout constraints. Evaluate the 0.5% initial accuracy against system tolerance needs compared to standard 1% variants.

Part Context

This part belongs to the TLVH431 family of low-voltage shunt regulators. It serves as a drop-in replacement for traditional TL431 devices but offers improved performance at lower supply voltages. The Q-prefix indicates automotive qualification, distinguishing it from commercial grade parts while maintaining functional compatibility within the broader reference voltage product line.
