Note 1: See thermal regulation specifications for changes in output voltage due to heating effects. Load line regulations are mea-
sured at a constant junction temperature by low duty cycle pulse testing.
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.
