c: VNOM6 refers to the nominal output voltage level for VOUT6 as defined by the Ordering Information section.
d: Dropout Voltage is defined as the differential voltage between input and output when the output voltage drops 100mV below the
regulation voltage at 1V differential voltage (for 2.8V output voltage or higher)
3: LDO current limit is defined as the output current at which the output voltage drops to 95% of the respective regulation voltage. Un-
der heavy overload conditions the output current limit folds back by 30% (typ)
