TLVH431BQDBVRE4

Overview

The TLVH431BQDBVRE4 is a low-voltage adjustable precision shunt regulator from Texas Instruments, housed in an SOT-23-5 package. It features an initial accuracy of 0.5% and a temperature coefficient of 138 PPM/C. The device supports an input voltage up to 20 V and an adjustable output range up to 18 V. Maximum shunt current is 80 mA, with a minimum operating current of 80 uA. It operates within a temperature range of -40 C to +125 C.

Feature Summary

• Provides high-precision voltage regulation with 0.5% initial accuracy for stable reference applications.
• Supports wide operating current ranges suitable for low-power and standard load conditions.
• Designed for automotive environments with extended temperature capability.

Applications

• Automotive power supply monitoring circuits
• Precision voltage reference generation
• Battery management system feedback loops

Procurement Notes

Verify the suffix E4 indicates lead-free compliance and RoHS standards. Confirm the Q designation ensures automotive qualification requirements are met. Check current availability status as this specific variant may have limited stock or end-of-life constraints compared to non-E4 versions.

Selection Notes

Select this component when 0.5% accuracy is required in an SOT-23-5 footprint. Ensure the application voltage does not exceed 20 V. Consider thermal performance at maximum shunt currents within the specified temperature range.

Part Context

This part belongs to the TLVH431B series, designed for low-voltage precision regulation. It serves as a drop-in replacement for standard TL431 devices where lower voltage operation and higher accuracy are needed. The E4 suffix denotes environmental compliance.

Replacement Considerations

Direct substitutes include TLVH431BQDBVR for non-E4 variants. Verify pin compatibility with SOT-23-5 packages before substitution.
