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