Note:

Dropout voltage is defined as the minimum input to output differential voltage at which the output drops 2%

below the nominal value. Dropout voltage specification applies only to output voltages of 2.5V and above. For

output voltages below 2.5V, the drop-out voltage is nothing but the input to output differential, since the

minimum input voltage is 2.5V.
