Overview
The TL432QDBZTG4 is an automotive-grade adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495V to 36V and supports a maximum cathode current of 100mA. The device features an initial accuracy of 2% and a maximum temperature coefficient of 92ppm/°C. It functions reliably across an operating temperature range from -40°C to +125°C, with a maximum input voltage of 37V. Packaged in a surface-mount SOT-23-3 format on a tape and reel, it meets automotive reliability standards.
Feature Summary
- Automotive-grade qualification for enhanced reliability in vehicle electronics
- Adjustable output voltage capability spanning 2.495V to 36V
- High thermal stability with low temperature coefficient specifications
Applications
- Automotive power supply regulation circuits
- Precision voltage reference sources in automotive modules
- Shunt regulation in automotive battery management systems
Procurement Notes
Verify the specific Q-series designation confirms automotive grade compliance against project requirements. Ensure the SOT-23-3 package dimensions align with PCB layout constraints. Confirm the tape and reel packaging matches automated assembly equipment specifications. Validate that the 2% initial accuracy meets circuit tolerance needs. Check RoHS and REACH compliance documentation for regulatory adherence.
Selection Notes
Select this component when automotive reliability and wide temperature operation are critical. The adjustable nature allows flexibility in setting reference voltages without external dividers. Consider the 100mA current capacity for load requirements. The SOT-23-3 package offers space efficiency for compact designs. Evaluate the 2% accuracy against stricter precision needs where lower tolerance variants might be necessary.
Part Context
This part belongs to the TL432 family of adjustable precision shunt regulators. It shares functional similarities with the TL431 but is optimized for automotive applications. The Q suffix indicates automotive qualification, distinguishing it from standard industrial grades. It serves as a key component in Texas Instruments' portfolio for robust power management solutions.
Replacement Considerations
Direct substitutes include other automotive-grade TL432 variants with matching package and electrical characteristics. Verify pinout compatibility before substitution. Cross-reference temperature ranges and accuracy specs to ensure equivalent performance in the target application.
