TLVH432AIPK

Overview

The TLVH432AIPK is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of 1% and a temperature coefficient of 138 ppm/°C. It supports a maximum cathode current of 80 mA with a minimum operating current of 80 µA. The component is housed in a SOT-89-3 surface-mount package and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V to 18 V for flexible circuit design
• High precision performance with 1% initial accuracy and stable operation over wide temperature ranges
• Low power consumption characterized by minimal minimum cathode current requirements

Applications

• Battery-powered equipment requiring precise voltage monitoring
• Portable devices utilizing low-voltage power supplies
• General-purpose voltage reference circuits in compact form factors

Procurement Notes

Verify the specific suffix IPK confirms the SOT-89-3 package and standard accuracy grade when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering quantity matches available packaging options such as cut tape or reel formats. Cross-reference the manufacturer part number against distributor databases to confirm current production status and availability.

Selection Notes

Select this component when a small surface-mount footprint is required alongside adjustable voltage referencing capabilities. The SOT-89-3 package offers a balance between thermal performance and space efficiency for portable applications. Consider the 1% accuracy specification against tighter tolerance alternatives if higher precision is necessary. Evaluate the 80 mA sink current capacity to ensure it meets the load requirements of the target circuit design.
