TL432AIDBZT

Overview

The TL432AIDBZT is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a SOT-23-3 surface-mount package. It provides an adjustable output voltage ranging from 2.495 V to 36 V with an initial accuracy of ±1%. The device supports a maximum cathode current of 100 mA and operates within a temperature range of -40°C to 85°C.

Feature Summary

• Adjustable output voltage set via external resistors
• High initial accuracy for precise reference applications
• Low dynamic output impedance for stable regulation

Applications

• Portable equipment power supplies
• Battery chargers
• Internal reference voltage sources

Procurement Notes

Verify the specific suffix DBZT confirms the SOT-23-3 tape-and-reel packaging configuration. Ensure the 'A' grade designation matches the required ±1% initial accuracy tolerance for the design. Confirm RoHS compliance status aligns with environmental regulations for the target market.

Selection Notes

Select this component when a compact three-terminal adjustable reference is needed in a small footprint. The SOT-23-3 package offers space efficiency compared to larger alternatives. Consider the ±1% accuracy and operating temperature range to ensure compatibility with system thermal and precision requirements.

Part Context

This part belongs to the TL432 family of adjustable shunt regulators. It shares functional similarities with the TL431 but utilizes a different pinout arrangement suitable for the SOT-23-3 package. The family is designed for general-purpose voltage referencing and regulation tasks in consumer and industrial electronics.

Replacement Considerations

NCP431ACSNT1G is a documented substitute option.
