TLVH431QDBVR

Overview

The TLVH431QDBVR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a 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 80 mA and has a maximum reference input voltage of 20 V. It exhibits a temperature coefficient of 138 PPM/C and functions reliably between -40°C and +125°C. Packaged in a SOT-23-5 format, this component serves as a precise voltage reference for various electronic circuits.

Feature Summary

Provides adjustable precision voltage regulation with low operating voltage capabilities
Features sharp turn-on characteristics suitable for replacing low-voltage Zener diodes
Designed for use in isolated feedback circuits when paired with optocouplers

Applications

Isolated feedback circuits in switch-mode power supplies
Board-level voltage regulation systems
Adjustable power supply implementations

Procurement Notes

Verify the specific suffix QDBVR against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the latest datasheet revision. Check for obsolescence notices or product change notifications prior to finalizing procurement decisions.

Selection Notes

Select this component when a low-voltage adjustable reference is required with moderate precision. Ensure the application demands a cathode current capability up to 80 mA. Verify that the operating temperature range aligns with the specified -40°C to +125°C limits for the intended environment.

Part Context

This part belongs to the TLVH431 series of low-voltage adjustable precision shunt regulators. It shares functional similarities with other industry-standard references but offers improved performance at lower voltages. The series includes variants with different accuracy grades and automotive qualifications.

Replacement Considerations

Direct substitutes include TLVH431AQDBVRQ1 and TLVH431BQDBVRQ1. These alternatives offer higher accuracy grades of 1% and 0.5% respectively while maintaining similar electrical characteristics and packaging.
