TLVH432CPKG3

Overview

The TLVH432CPKG3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of up to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of ±1.5% and a temperature coefficient of 138 PPM/°C. It supports a maximum cathode current of 70 mA with a minimum operating current of 100 µA. The component functions reliably across an extended temperature range of -40°C to +125°C and is housed in a SOT-89-3 surface-mount package.

Feature Summary

• Adjustable precision shunt regulation with wide output voltage range
• High initial accuracy for stable reference performance
• Extended industrial temperature rating for harsh environments

Applications

• Portable equipment power management
• Battery-powered systems requiring precise voltage references
• Industrial control circuits needing stable shunt regulation

Procurement Notes

Verify the specific suffix PKG3 confirms the SOT-89-3 package variant during sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the procurement channel sources genuine Texas Instruments components to guarantee specified electrical parameters and reliability standards are met for production integration.

Selection Notes

Select this component when a compact SOT-89-3 footprint is required for adjustable voltage referencing. Choose based on the need for ±1.5% initial accuracy and operation up to 125°C. Consider the 70 mA cathode current limit for load requirements. Verify compatibility with system input voltages not exceeding 20 V.

Part Context

This part belongs to the TLVH432 series of low-voltage adjustable precision shunt regulators. It serves as a cost-effective alternative to traditional Zener diodes, offering superior accuracy and temperature stability. The series is designed for applications requiring reliable voltage reference or simple overvoltage protection in space-constrained designs.

Replacement Considerations

Direct replacements may include other Texas Instruments parts within the TLVH432 family with compatible packages. Verify pinout compatibility and electrical specifications such as current limits and accuracy grades before substituting. Cross-reference datasheets to ensure thermal and voltage ratings match the original design requirements.
