ADP3338 - 5V output with 0V input

I'm designing a system for a car with two use cases. In normal operation, the system is powered by the 12V car battery, which is regulated to 5.6V by a buck-boost regulator and then to 5V by the ADP3338. When the system is outside of the car, however, it needs to be powered by USB (through a diode).


My question is if the ADP3338 can handle 5V at the output while its input is at 0V.


Thanks!
