Overview
The TL432QDBVRG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495 V to 36 V and features an initial accuracy of 2.2%. The device supports a maximum cathode current of 100 mA and has a minimum cathode current of 80 µA. It is housed in a SOT-23-5 package with surface mount installation. The component functions reliably across a temperature range of -40°C to +125°C, with a maximum series input voltage of 37 V.
Feature Summary
- Provides adjustable precision voltage regulation via external resistor network
- Operates over extended industrial temperature ranges for automotive applications
- Supports high cathode current capacity for robust load handling
Applications
- Automotive power supply circuits requiring AEC-Q100 qualification
- Precision voltage reference sources in battery management systems
- Feedback loop compensation in switching regulators
Procurement Notes
Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the latest manufacturer documentation. Confirm the Q-series designation aligns with required automotive reliability standards for your specific application environment. Ensure the SOT-23-5 footprint matches your PCB layout constraints before finalizing procurement orders.
Selection Notes
Select this component when automotive-grade reliability and wide operating temperature ranges are mandatory. The 2.2% initial accuracy offers a balance between cost and precision for general regulation tasks. Consider the 100 mA current capability if driving moderate loads directly without additional amplification stages.
Part Context
This part belongs to the TL432 family of adjustable precision shunt regulators from Texas Instruments. It serves as a semiconductor alternative to discrete zener diodes, offering superior stability and lower dynamic impedance. The Q-series variant specifically targets automotive electronics markets requiring stringent quality and longevity standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with direct pin-to-pin replacements such as other TL432 variants or equivalent shunt regulators only after consulting official cross-reference guides.
