TL432AQDBZRQ1

Overview

The TL432AQDBZRQ1 is an automotive-grade adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.495 V to 36 V and features an initial accuracy of 1%. The device has a temperature coefficient of 92 PPM/°C and supports a maximum cathode current of 100 mA. It functions reliably across a temperature range of -40°C to +125°C. Packaged in a SOT-23-3 surface-mount case, it meets AEC-Q100 qualification standards for automotive applications.

Feature Summary

AEC-Q100 qualified for automotive reliability requirements
Adjustable output voltage via external resistors
High initial accuracy with low temperature drift
All-capacitor stable operation without compensation

Applications

Automotive power supply regulation
Battery management systems
Precision voltage references in harsh environments
Switching power supply feedback loops

Procurement Notes

Verify the specific suffix Q1 confirms AEC-Q100 automotive qualification status before integration. Ensure the SOT-23-3 package footprint matches the target PCB design constraints. Confirm that the 1% initial accuracy meets the system's tolerance requirements at the operating temperature extremes defined in the datasheet specifications.

Selection Notes

Select this component when automotive certification is mandatory for the application. The wide input voltage range allows flexibility in circuit design compared to fixed reference devices. Consider the thermal performance within the -40°C to +125°C range to ensure stability under varying environmental conditions typical in vehicle electronics.

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 configuration suitable for compact surface-mount designs. The AQ variant denotes specific accuracy and temperature characteristics optimized for high-reliability industrial and automotive sectors.
