Overview
The ATL432LIBQDBZRQ1 is an automotive-grade, high-bandwidth, low-quiescent current programmable shunt regulator manufactured by Texas Instruments. It operates within a temperature range of -40°C to +125°C and utilizes a 3-pin SOT-23 package. The device features AEC-Q100 qualification for automotive applications. Its adjustable output voltage ranges from approximately 2.5V to 36V, determined by external resistors. The component offers low initial accuracy tolerance and stable performance across varying thermal conditions, suitable for precision reference and regulation tasks in demanding environments.
Feature Summary
- Automotive-grade reliability with AEC-Q100 qualification
- High bandwidth capability for fast transient response
- Low quiescent current consumption for energy efficiency
- Adjustable output voltage via external resistor network
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 package, temperature grade, and tape/reel configuration. Confirm AEC-Q100 compliance requirements match specific vehicle standards. Check for recent production changes or obsolescence notices directly from Texas Instruments documentation before finalizing procurement specifications.
Selection Notes
Select this component when automotive certification and high-speed regulation are required. Compare bandwidth and quiescent current specifications against standard TL432 variants if cost sensitivity outweighs performance needs. Ensure the SOT-23 package fits the PCB layout constraints. Validate that the input voltage range exceeds the maximum expected circuit potential.
Part Context
This device belongs to the ATL43x family of programmable shunt regulators designed specifically for automotive electronics. It shares functional similarities with the commercial TL432 series but includes enhanced testing and reliability qualifications required for automotive use. The family provides a compact solution for voltage referencing and regulation in space-constrained automotive modules.
Replacement Considerations
The TL432LIBQDBZRQ1 serves as a direct automotive-compatible alternative to non-automotive TL432 variants where qualification is mandatory. Verify pinout compatibility with existing designs using the DBZR package. Cross-reference with ATL431 series only if lower voltage operation suffices.
