(whichever is greater).

4: Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below

its nominal value measured at 1V differential. For outputs below 1.65V, dropout voltage is considered the

input-to-output voltage differential with the minimum input voltage of 1.65V. Minimum input operating volt-

age is 1.65V.
