TLVH432ACPKG3

Overview

The TLVH432ACPKG3 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range 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% and a temperature coefficient of 138 PPM/°C. It supports a maximum shunt current of 80 mA with a minimum cathode current of 80 µA. The component functions reliably across an extended operating temperature range of -40°C to +125°C. It is housed in a surface-mount SOT-89-3 package.

Feature Summary

Adjustable precision shunt regulation with wide output voltage range
High initial accuracy for stable reference performance
Extended industrial temperature operation capability

Applications

Precision voltage reference circuits
Low-voltage power supply monitoring
Battery-powered system regulation

Procurement Notes

Verify the specific suffix 'CPKG3' against official Texas Instruments documentation, as standard listings typically utilize 'IPK'. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to procurement. Ensure the sourcing channel provides valid traceability for automotive or industrial qualification requirements if applicable.

Selection Notes

Select this component when a compact SOT-89-3 form factor is required alongside high accuracy specifications. Compare the 1% initial tolerance against tighter 0.5% alternatives like the B-grade variants if stricter precision is needed. Evaluate the thermal management capabilities of the SOT-89 package for the intended power dissipation levels.

Part Context

This part belongs to the TLVH432 family of low-voltage adjustable shunt regulators. It shares functional similarities with the TLVH431 series but offers optimized performance characteristics for modern low-power applications. The family is designed to replace older discrete zener diode solutions with integrated precision regulation.
