Overview
The TL432LIBQDBZRQ1 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 0.5%. The device supports a maximum cathode current of 15 mA and maintains a temperature coefficient of 63 PPM/°C. It functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount case, it meets AEC-Q100 qualification standards for automotive applications.
Feature Summary
- Automotive-grade reliability with AEC-Q100 qualification
- High precision with 0.5% initial accuracy
- Low temperature drift for stable performance
- Compact three-terminal SOT-23-3 package
Applications
- Automotive power supply regulation
- Battery management systems
- Precision voltage references in harsh environments
Procurement Notes
Verify the complete part number including suffixes to ensure correct automotive qualification and package type. Confirm RoHS compliance status through official documentation. Check for specific tape-and-reel specifications if automated assembly is required. Ensure compatibility with existing PCB footprints for the SOT-23-3 package. Validate thermal requirements against the specified operating temperature range.
Selection Notes
Select this component when high precision and automotive reliability are required in space-constrained designs. The low temperature coefficient ensures stability across wide thermal variations typical in vehicle environments. Compare cathode current limits against load requirements to ensure adequate headroom. Consider the SOT-23-3 footprint constraints during layout planning.
Part Context
This device belongs to the TL432LI family of adjustable shunt regulators designed specifically for automotive applications. It shares functional similarities with commercial counterparts but offers enhanced reliability and stricter parameter controls. The LI designation indicates improved line regulation characteristics compared to standard variants.
Replacement Considerations
Direct replacements must match the SOT-23-3 package and AEC-Q100 qualification. Verify that substitute parts maintain the 0.5% accuracy and 63 PPM/°C temperature coefficient. Ensure compatible cathode current capabilities for the specific application load.
