TL432QDBZT

Overview

The TL432QDBZT is an adjustable precision shunt regulator manufactured by Texas Instruments, designed for automotive applications. It operates within a supply voltage range of 2.5 V to 36 V and provides an adjustable output voltage from 2.495 V to 36 V. The device features an initial accuracy of ±2% and a temperature coefficient of 92 PPM/°C. It supports a maximum cathode current of 100 mA with a minimum operating current of 600 µA. The component functions reliably across an extended temperature range from -40°C to +125°C and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

Automotive-grade qualification ensuring reliability in demanding environments
Wide input voltage range supporting high-voltage reference applications
High initial accuracy for precise voltage regulation requirements

Applications

Automotive power supply monitoring circuits
Voltage reference for analog-to-digital converters
Battery management system feedback loops

Procurement Notes

Verify the specific suffix 'Q' confirms automotive grade qualification against the official datasheet. Confirm the 'DBZT' suffix indicates the SOT-23-3 package and tape-and-reel quantity. Ensure the part number matches the exact tolerance and temperature coefficient specifications required for the design. Cross-reference the manufacturer's latest documentation for any pinout or electrical parameter updates.

Selection Notes

Select this component when automotive reliability and wide voltage operation are required. Compare the ±2% initial accuracy against tighter tolerance alternatives if higher precision is needed. Evaluate the 100 mA cathode current capability against load requirements. Consider the SOT-23-3 package size constraints relative to available board space. Verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to the TL432 family of adjustable shunt regulators from Texas Instruments. It shares functional similarities with the TL431 but offers a wider input voltage range up to 36 V. The Q-series designation typically denotes automotive-grade components meeting specific reliability standards. It serves as a cost-effective solution for voltage referencing in industrial and automotive systems.
