Note 1) 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 2.5V, dropout voltage is the input-to-output voltage differential
with the minimum input voltage 2.6V
Note 2) Ground pin current is the regulator quiescent current. The total current drawn from the supply is the sum of the load
current plus the ground pin current.
