Guaranteed by design.
Regulation is measured at constant junction temperature, using pulse testing with a low ON time.
Current limit is measured by pulsing a short time.
Dropout voltage is defined as the input to output differential at which the output voltage drops
100mV below the value measured with a 1V differential.
