The quiescent current is measured in standby mode when R
The dropout voltage of regulator 3 is the voltage difference between V
The dropout voltage of a regulator is the voltage difference between V
At current limit, V
The foldback current protection limits the dissipation power at short-circuit; see
The dropout voltage of regulator 2 is the voltage difference between V
Unbiased switch-supply I
Regulator output still in regulation at applied test voltage, therefore the actual dropout voltage can not be measured.
