Note 1: The dropout voltage varies depending on output voltage selection. Dropout is defined as VIN–VOUT when VOUT is 100mV
below nominal VOUT where Vin=Vout + 1V for nominal VOUT
.
Note 2: PSRR is tested at Vin=3.8+1Vppac, Vout=2.8V, I_load=1mA.
Note 3: Time needed for VOUT to reach 90% of final value.
