Frequently Asked Questions
What output current and automotive qualification does the TPS73201QDBVRVS carry?
The TPS73201QDBVRVS provides a maximum output current of 250 mA and is qualified to AEC-Q100 Grade, the automotive industry standard for IC reliability. This qualification includes temperature cycling, humidity testing, and ESD stress validation, making it suitable for safety-relevant automotive power supply rails.
How does reverse current protection in the TPS73201QDBVRVS benefit automotive start-stop systems?
In automotive start-stop systems, the supply voltage can momentarily drop below the regulated output voltage during engine restart. The reverse current protection in the TPS73201QDBVRVS prevents current from flowing backward from the load capacitor or downstream circuitry into the input, protecting sensitive 250 mA-rated rails from reverse transient damage.
What PCB footprint does the TPS73201QDBVRVS require and how does it compare to larger LDO packages?
The TPS73201QDBVRVS uses a 5-pin SOT-23 package with a footprint of approximately 2.9 mm x 1.6 mm, significantly smaller than 8-pin SOIC or TO-252 packages used by higher-current LDOs. This compact outline allows placement close to load ICs in space-constrained automotive PCBs such as ADAS camera modules and instrument clusters.
