Note1 : The drop out voltage varies depending on output voltage selection
Dropout is defined as VIN – VOUT when VOUT is 100mV below VOUT where Vin=Vout + 1V for nominal
VOUT
.
Note 2: Time needed for VOUT to reach 90% of final value.
Typical Characteristics
At TA=25℃, VIN=(VOUT+0.5V), CIN=COUT=0.47µF, VEN=VIN, unless otherwise noted.
