Note 2: Dropout voltage is specified over the full output current range of
the device. Dropout voltage is defined as the minimum input/output
differential measured at the specified output current. Test points and limits
are also shown on the Dropout Voltage curve.
Note 3: Minimum load current is defined as the minimum output current
required to maintain regulation.
