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+0.5V), C_IN=C_OUT=0.47µF, V_EN=V_IN, unless otherwise noted.
