TLVH431AQDBZRG4

Overview

The TLVH431AQDBZRG4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It features an initial accuracy of 1% and operates within a temperature range of -40°C to +125°C. The device supports an output voltage adjustment from 1.24 V to 18 V, with a maximum input voltage of 20 V. It offers a maximum shunt current of 70 mA and a minimum operating current of 80 uA. The unit utilizes an SC-70-6 surface-mount package and carries AEC-Q100 qualification for automotive applications.

Feature Summary

AEC-Q100 qualified for automotive reliability standards
Low-voltage operation with wide operating current range
High precision with 1% initial accuracy
Extended industrial temperature performance

Applications

Automotive power management systems
Precision voltage reference circuits
Battery management system monitoring
Industrial control loop feedback

Procurement Notes

Verify the specific suffix 'RG4' against official Texas Instruments documentation to confirm the exact reel quantity and packaging configuration. Ensure that the SC-70-6 package dimensions align with the target PCB footprint requirements. Confirm that the AEC-Q100 qualification status meets the specific automotive grade requirements of the end application before finalizing procurement orders.

Selection Notes

Select this component when high precision is required in space-constrained automotive designs. The SC-70-6 package provides a compact solution compared to larger alternatives. Consider the 70 mA maximum shunt current limit for load driving capabilities. The extended temperature range makes it suitable for harsh automotive environments where standard commercial parts may fail.

Part Context

This part belongs to the TLVH431A series of low-voltage adjustable precision shunt regulators. It serves as a modern alternative to traditional TL431 devices, offering improved performance at lower voltages. The series is designed specifically for applications requiring tight tolerance and stability in compact form factors.
