TLV431BIDBVT

Overview

The TLV431BIDBVT is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 6 V and features an initial accuracy of 0.5%. The device supports a maximum cathode current of 15 mA and has a maximum reference input voltage of 7 V. It functions reliably across an operating temperature range from -40 °C to +85 °C with a temperature coefficient of 138 ppm/°C. The component is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• Provides high-precision voltage regulation with 0.5% initial accuracy for stable reference applications
• Operates at low voltages with an adjustable output range starting from 1.24 V
• Designed for space-constrained designs using a small SOT-23-5 surface-mount package

Applications

• Precision voltage references in battery-powered equipment
• Feedback control loops in switching power supplies
• Comparator circuits requiring accurate threshold levels

Procurement Notes

Verify the specific suffix IDBVT corresponds to the standard commercial grade variant rather than automotive or extended temperature grades. Confirm RoHS compliance status and lead times through authorized distributors. Ensure the ordering quantity matches the manufacturer's standard packaging requirements to avoid handling fees or availability issues during procurement.

Selection Notes

Select this component when a low-voltage adjustable reference with tight 0.5% accuracy is required. It serves as a direct replacement for standard TL431 devices in low-voltage systems where higher supply voltages are unnecessary. Consider the 15 mA current limit and 7 V max input voltage constraints when designing the feedback network and load conditions.

Part Context

This part belongs to the TLV431 family of low-voltage adjustable precision shunt regulators. It shares functional similarities with the TL431 but is optimized for lower voltage operation, typically ranging from 1.24 V to 6 V. The family includes variants with different accuracy grades and temperature ranges, such as the TLV431A and TLV431C, offering flexibility for various precision analog applications.

Replacement Considerations

Direct substitutes include the TLV431AI DBVT and TLV431CIDBVT for different accuracy grades. For higher voltage applications, the TL431BCDBVT may be considered if the system voltage exceeds 7 V. Verify pinout compatibility and thermal performance when swapping between these variants.
