Specifications are guaranteed by Statistical Quality Control (SQC), not by 100% production
testing, over the operating temperature range from -40°C to 85°C.
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 of the output voltage measured with a 1V differential.
