TLVH431BQLPRE3

Overview

The TLVH431BQLPRE3 is an adjustable precision shunt voltage reference manufactured by Texas Instruments. It operates within a supply voltage range of up to 36 V and supports a maximum cathode current of 100 mA, with a minimum operating current of 600 uA. The device features an initial accuracy of 0.5% and a temperature coefficient of 92 PPM/C. It functions reliably across a temperature range from -40 C to +125 C. The component is housed in a TO-92-3 through-hole package and belongs to the TL431B series.

Feature Summary

• Provides adjustable output voltage capability for precise circuit regulation
• Ensures stable performance over a wide industrial temperature range
• Delivers high initial accuracy for reliable reference applications

Applications

• Battery-operated equipment requiring low power consumption
• Switch mode power supplies needing stable reference voltages
• Data acquisition systems utilizing precision analog references

Procurement Notes

Verify component authenticity against official Texas Instruments documentation before integration. Confirm that the specific suffix matches the required package and tolerance specifications. Check for end-of-life status or obsolescence notices as availability may be limited. Ensure compatibility with existing PCB footprints and thermal management requirements during the procurement phase.

Selection Notes

Select this component when a through-hole adjustable shunt regulator with 0.5% accuracy is required. Consider the 100 mA sink current capability for load driving needs. Evaluate the 92 PPM/C temperature coefficient against thermal stability requirements. Compare against surface-mount alternatives if board space constraints exist, noting the TO-92-3 package dimensions.

Part Context

This part belongs to the TLVH431 family of low-voltage adjustable shunt regulators. It shares functional similarities with the standard TL431 but offers optimized characteristics for specific efficiency and voltage ranges. The B suffix indicates a 0.5% initial accuracy grade, distinguishing it from lower precision variants within the broader product line.
