Electrical Characteristics
Table 2
Note 1 : The drop out voltage varies depending on output voltage selection
Dropout is defined as VIN–VO when VO is 100mV below VO where VIN=Max(VO1,VO2) for nominal VO.
Note 2: Time needed for VOUT to reach 90% of final value.
TA = 25℃, VIN= Max(VO1,VO2) + 1 V , CIN = COU T1= Cout2=1.0μF, EN = VIN, unless otherwise noted
