TLVH432IPK

Overview

The TLVH432AIPK 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 initial accuracy of ±1%. The device supports a maximum cathode current of 70 mA and functions across a temperature range of -40°C to 85°C. Packaged in a SOT-89-3 surface-mount case, it serves as a high-precision reference for power management applications requiring stable voltage regulation.

Feature Summary

• Adjustable output voltage capability spanning from the internal reference level up to the maximum supply limit
• High initial accuracy specification ensuring precise voltage referencing under varying conditions
• Low voltage operation optimized for modern portable and battery-powered electronic systems

Applications

• Portable equipment requiring stable low-voltage references
• Battery-powered measurement instruments
• Power supply feedback loops
• Voltage monitoring circuits

Procurement Notes

Verify the specific suffix 'A' in TLVH432AIPK against official datasheets to confirm the ±1% tolerance grade. Ensure the SOT-89-3 package matches the design footprint. Confirm RoHS compliance status with the manufacturer before finalizing procurement specifications.

Selection Notes

Select this component when a ±1% accuracy is required within the 18 V operating range. Compare against TLVH432QPKG3 if automotive qualification or extended temperature ranges are necessary. Verify that the 70 mA cathode current meets the circuit load requirements.

Part Context

This part belongs to the TLVH43x family of low-voltage shunt regulators. It shares functional similarities with the TLVH431 series but offers distinct accuracy and current characteristics. The IPK suffix denotes the SOT-89-3 surface-mount package configuration used in compact designs.

Replacement Considerations

TLVH432QPKG3 is a qualified alternative offering similar functionality with potential automotive grade specifications.
