1. “Non operating” should be intended as a condition outside the absolute maximum ratings defined for the IC. As such, if the
device is operated under such conditions, it is not guaranteed that the electrical parameters are inside the specification
range.
2. Drop condition means that the supply voltage drop down to 100 mV from the regulated output and the regulator is sourcing
its maximal load current.
