TLVH431IPKG3

Overview

The TLVH431IPKG3 is a three-terminal adjustable precision shunt voltage reference manufactured by Texas Instruments. It operates within an input voltage range of 2.495 V to 36 V and provides an adjustable output voltage. The device features a maximum cathode current of 100 mA and maintains an initial accuracy of ±1%. It is designed for operation across an extended temperature range from -40 °C to +85 °C. The component is housed in a SOT-89 package with three pins, suitable for surface-mount applications requiring precise voltage regulation.

Feature Summary

• Adjustable output voltage capability spanning from 2.495 V up to 36 V
• High precision performance with ±1% initial accuracy tolerance
• Robust current handling with a maximum cathode current of 100 mA
• Automotive qualification supporting reliable operation in vehicle environments

Applications

• Automotive power supply voltage monitoring circuits
• Precision voltage reference sources for analog-to-digital converters
• Battery management system voltage sensing
• Industrial control loop feedback references

Procurement Notes

Verify the specific suffix 'IPKG3' against the official Texas Instruments datasheet to confirm pinout compatibility and RoHS status. Ensure the sourcing channel provides valid traceability documentation for automotive-grade components. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit units. Confirm that the SOT-89 package variant matches the intended PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a wide input voltage range up to 36 V is required compared to standard 2.5 V references. The ±1% accuracy suits applications needing tighter tolerances than basic zener diodes. Consider the SOT-89 package for space-constrained designs requiring higher current capacity than SOT-23 options. Verify thermal dissipation capabilities within the -40 °C to +85 °C operating range for the specific enclosure environment.

Part Context

This device belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. It serves as a high-performance alternative to traditional bandgap references, offering wider voltage adjustability. The family is characterized by low dynamic impedance and high ripple rejection ratios. It complements other Texas Instruments PMIC solutions by providing stable reference points for complex power management architectures.
