Key Features
- AEC-Q100 automotive qualification ensuring reliable 3.3V regulation across the full automotive temperature range in demanding underhood and cabin electronics
- 0.3V nominal dropout voltage enabling 3.3V output from battery voltages as low as 4.3V, minimizing headroom loss in 5V automotive bus-powered designs
- 0.019% maximum line regulation across the 4.3V to 10V input range in a compact 5-pin SOT-23 package, reducing external component count for space-constrained automotive PCBs
Applications
TPS76333QDBVRQ1 provides a stable 3.3V supply rail for automotive microcontrollers, CAN transceivers, and sensor interfaces in body control modules and infotainment systems. Its AEC-Q100 qualification and wide 4.3V to 10V input range accommodate the voltage transients and load dumps present on automotive 12V battery rails. ADAS sensor power supplies, telematics units, and keyless entry systems also use this device where a compact 5-pin SOT-23 footprint and automotive reliability are required alongside low-noise 3.3V regulation.

Frequently Asked Questions
How does TPS76333QDBVRQ1's 0.3V dropout voltage extend usable battery discharge range in an automotive 12V system?
With a 0.3V nominal dropout voltage, TPS76333QDBVRQ1 maintains a regulated 3.3V output as long as the input battery voltage stays above 3.6V, well below the 4.3V minimum specified input. In an automotive start-stop system where battery voltage can sag to 6V during cranking, the 0.3V dropout ensures the 3.3V rail stays in regulation with 2.7V of headroom, preventing MCU resets that would occur with a 1V to 2V dropout competitor. This characteristic extends reliable system operation through the full battery discharge cycle.
What does AEC-Q100 qualification mean for TPS76333QDBVRQ1 in an ADAS sensor application, and what temperature grade applies?
AEC-Q100 is the Automotive Electronics Council stress test qualification standard for ICs used in vehicles, requiring devices to pass accelerated life tests including high-temperature operating life (HTOL) at 125°C, temperature cycling between -40°C and 150°C, and electrostatic discharge immunity. TPS76333QDBVRQ1's Q1 suffix indicates Grade 1 qualification covering -40°C to 125°C ambient temperature range, which encompasses the operating environment of ADAS radar and camera sensors mounted in engine compartments and exterior locations. This certification gives automotive OEMs confidence in the device's long-term reliability over the 10-to-15-year vehicle lifetime.
For a 5V USB-powered automotive dongle design, can TPS76333QDBVRQ1 supply 3.3V directly from a 5V USB input within its specified input range?
Yes, a 5V USB power source falls within TPS76333QDBVRQ1's 4.3V to 10V input voltage range, and the 3.3V fixed output provides 1.7V of headroom well above the 0.3V nominal dropout. The device's 0.019% maximum line regulation ensures the 3.3V output remains stable even when the USB supply fluctuates between 4.75V and 5.25V under load variation, making it a drop-in solution for OBD-II dongles, fleet telematics USB adapters, and automotive-grade USB hubs requiring a clean 3.3V logic rail from the vehicle's USB power port.
