TLVH431QDCKT

Overview

The TLVH431QDCKT is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 18 V and features an initial accuracy of ±1.5%. The device supports a maximum cathode current of 70 mA and withstands a maximum reference input voltage of 20 V. It functions reliably across a temperature range of -40°C to +125°C and utilizes a SC-70-6 surface-mount package.

Feature Summary

• Provides adjustable precision voltage regulation with low-voltage operation capabilities
• Ensures stable performance through wide operating current ranges
• Designed for automotive applications with qualified reliability standards

Applications

• Automotive power management systems
• Battery-powered equipment voltage references
• Low-voltage circuit regulation

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 automotive qualification status before integration. Confirm the 'DCK' designation matches the required SC-70-6 footprint dimensions. Ensure the 'T' indicates tape-and-reel packaging suitable for automated assembly processes. Cross-reference the manufacturer part number against official datasheets to validate electrical tolerances.

Selection Notes

Select this component when automotive-grade reliability is required alongside precise low-voltage regulation. The SC-70-6 package offers space efficiency for compact designs. Consider the 1.5% initial accuracy and 70 mA current capability against load requirements. Verify compatibility with system voltage ranges not exceeding 20 V.

Part Context

This part belongs to the TLVH431 series, which focuses on low-voltage adjustable shunt regulators. Unlike standard TL431 variants, this series supports lower minimum operating voltages starting at 1.24 V. The Q-series designation specifically targets automotive markets requiring enhanced quality and durability standards.
