Key Features
- 500 mA output current capability with 40 V maximum input and only 370 mV typical dropout voltage for automotive battery-rail applications
- Ultra-low quiescent current design extends battery life in always-on automotive subsystems such as key-off standby circuits
- Integrated power-good output flag enables system supervisors to sequence supply rails safely in ADAS and body control designs
Applications
The TPS7B8633DQDDARQ1 is designed for always-on automotive subsystems such as ECU standby circuits, infotainment keep-alive rails, and body control modules that must operate from a 40 V automotive battery with minimal quiescent current drain. Its 500 mA current capacity and power-good output make it suitable for powering microcontrollers, sensors, and CAN transceivers in ADAS and gateway modules. The AEC-Q100 qualified device supports extended -40°C to +125°C temperature operation required for under-hood automotive electronics.

Frequently Asked Questions
What is the dropout voltage of the TPS7B8633DQDDARQ1 at 500 mA output and why does this matter for 12 V automotive systems?
The TPS7B8633DQDDARQ1 has a typical dropout voltage of 370 mV and a maximum of 535 mV at full 500 mA output load, ensuring the regulator maintains its 3.3 V fixed output even when the 12 V automotive battery drops to approximately 4.3 V minimum input during cold-crank conditions.
How does the TPS7B8633DQDDARQ1 handle load dump transients in automotive applications with 40 V input rating?
The TPS7B8633DQDDARQ1 accepts input voltages up to 40 V continuously (42 V absolute maximum), providing inherent protection against ISO 7637 load dump transients common on 12 V automotive battery rails where transient spikes can reach 40 V, eliminating the need for an external suppressor in most designs.
What does the power-good output on the TPS7B8633DQDDARQ1 enable in multi-rail automotive ECU power sequencing?
The power-good pin on the TPS7B8633DQDDARQ1 asserts a logic signal when the output voltage reaches its regulation target (typically within 5% of 3.3 V), allowing a supervisor IC or MCU to delay enabling downstream supply rails or releasing reset lines until the LDO output is stable, preventing undefined startup states in ADAS processors.
Over what temperature range is the TPS7B8633DQDDARQ1 rated for under-hood automotive installation?
The TPS7B8633DQDDARQ1 is AEC-Q100 qualified and rated for operation from -40°C to +125°C junction temperature, covering both arctic cold-start conditions and the elevated ambient temperatures found near automotive engine compartments and transmission controllers.
