TLVH432AIPKG3

Overview

The TLVH432AIPKG3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It provides an adjustable output voltage ranging from 1.24 V to 18 V with an initial accuracy of ±1%. The device operates within a maximum series input voltage of 20 V and supports a maximum cathode current of 80 mA, with a minimum operating current of 80 µA. It features a temperature coefficient of 138 PPM/°C and functions across a temperature range of -40°C to +125°C. Packaged in a SOT-89-3 surface-mount case, it is RoHS compliant and classified as a humidity-sensitive level 2 component.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V up to 18 V for flexible circuit design
• High initial accuracy of ±1% ensures precise voltage reference performance
• Extended industrial temperature operation range supporting -40°C to +125°C environments

Applications

• Precision voltage reference sources in battery-powered instrumentation
• Low-voltage power supply regulation circuits
• Portable electronic device power management systems

Procurement Notes

Verify the specific suffix 'G3' indicates lead-free packaging compliance when sourcing. Confirm the package designation matches the required SOT-89-3 footprint for PCB layout compatibility. Check manufacturer documentation for any recent Product Change Notifications (PCN) regarding marking or assembly updates. Ensure handling procedures account for the specified moisture sensitivity level during storage and reflow soldering processes.

Selection Notes

Select this component when a compact surface-mount solution is required for low-voltage applications demanding high accuracy. The SOT-89-3 package offers a balance between thermal performance and board space efficiency. Consider the 138 PPM/°C temperature coefficient if strict thermal stability is necessary across wide environmental variations. Verify that the 80 mA cathode current limit meets the load requirements of the target application.

Part Context

This part belongs to the TLVH432 family of low-voltage adjustable precision shunt regulators. It serves as a modern alternative to traditional three-terminal references, offering improved performance in smaller packages. The family is designed for cost-sensitive and space-constrained applications requiring reliable voltage regulation without the need for external components.

Replacement Considerations

The TLVH432AIPK is a direct pin-compatible substitute within the same series. For automotive-grade requirements, consider the TLVH432AQPKG3 variant. The TLVH431AIPKG3 may be suitable if a lower maximum output voltage is acceptable.
