TLVH432IDBZT

Overview

The TLVH432IDBZT is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a compact SOT-23-3 surface-mount package. It provides an adjustable output voltage range from 1.24 V to 18 V with an initial accuracy of ±1.5%. The device supports a maximum cathode current of 70 mA and operates within a temperature range of -40°C to +85°C. Designed for low-voltage applications, it features a maximum series reference input voltage of 20 V and a low minimum operating current of 100 µA.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V up to 18 V
• High initial accuracy of ±1.5% for precise voltage referencing
• Low minimum operating current requirement of 100 µA
• Compact three-terminal SOT-23-3 surface-mount packaging

Applications

• Battery-powered portable electronic devices
• Low-voltage power supply regulation circuits
• General-purpose voltage reference modules
• Portable instrumentation systems

Procurement Notes

Verify the specific suffix 'IDBZT' to confirm the ±1.5% accuracy grade and standard operating temperature range. Ensure the procurement order specifies the correct tape-and-reel quantity if automated assembly is required. Cross-reference the manufacturer part number against official distributors to avoid counterfeit components. Confirm RoHS compliance status matches project requirements before finalizing orders.

Selection Notes

Select this component when a low-voltage adjustable reference is needed in a minimal footprint. The ±1.5% accuracy suits general applications where tighter tolerances are unnecessary. Compare the 70 mA cathode current limit against load requirements. Consider the -40°C to +85°C range for industrial or consumer environments. Evaluate the 100 µA minimum current against standby power constraints.

Part Context

This device belongs to the TLVH432 family of low-voltage precision shunt regulators from Texas Instruments. It shares architectural similarities with the TL432 series but is optimized for lower input voltage operations up to 20 V. The family utilizes a bandgap reference topology to maintain stability across varying temperatures and load conditions within the specified operational envelope.
