Output leakage is measured with the current pins in high impedance.
See the USB 2.0 Specification, Chapter 7, for USB DC electrical characteristics
RBIAS is a 3.3V tolerant analog pin.
Output current range is controlled by program software. The software disables the FET
during short circuit condition.
The 3.3V supply should be at least at 75% of its operating condition before the 1.8V supply
is allowed to ramp up.
