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.
Specifications are guaranteed by Statistical Quality Controls (SQC), with no production test proved,
when operating temperature ranges from -40°C to 85°C.
