TLVH431IDBVT

Overview

The TLVH431IDBVT is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 1.24 V to 18 V and provides an adjustable output voltage across the same span. The device features an initial accuracy of ±1.5% and a temperature coefficient of 138 ppm/°C. It supports a maximum cathode current of 70 mA and functions reliably within an operating temperature range of -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount case, it serves as a high-performance reference solution for space-constrained designs.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V up to 18 V
• Precision regulation with ±1.5% initial accuracy specification
• Extended industrial temperature operation ranging from -40°C to +125°C

Applications

• Battery-powered equipment requiring precise voltage references
• Portable devices utilizing low-voltage power supplies
• General-purpose voltage regulation circuits

Procurement Notes

Verify the specific suffix IDBVT confirms the SOT-23-3 package and 1.5% accuracy grade when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to final procurement decisions. Ensure the component matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when an adjustable shunt regulator is needed with ±1.5% accuracy and operation up to 18 V. The SOT-23-3 package suits applications with strict board space limitations. Consider the 70 mA cathode current limit for load requirements. Verify that the 138 ppm/°C temperature coefficient meets the system's stability needs across the specified industrial temperature range.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators from Texas Instruments. The family includes variants with different accuracies and packages, such as the TLVH431A series offering higher precision. The TLVH431IDBVT specifically targets cost-sensitive applications requiring moderate accuracy in a small footprint, distinguishing it from the standard TLV431 series.

Replacement Considerations

Direct substitutes include other TLVH431 variants like TLVH431IDBZT, which shares the same electrical characteristics but may differ in packaging or reel specifications. Cross-referencing with the TLV431 family is possible if lower performance thresholds are acceptable.
