c: VNOM refers to the nominal output voltage level for VOUT as defined by the Ordering Information section.
2: IMAX Maximum Output Current.
3: 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).
f: 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)
