: VNOM refers to the nominal output voltage level for VOUT as defined by the Ordering Information section.



: IMAX Maximum Output Current.



: Dropout Voltage is defined as the differential voltage between input and output when the output voltage drops 100mV below the regulation voltage (for 3.1V output

voltage or higher).



: LDO current limit is defined as the output current at which the output voltage drops to 95% of the respective regulation voltage. Under heavy overload conditions the

output current limit folds back by 50% (typ.)
