output voltage, the current limit is defined as the current that causes the output voltage to drop to 90% of 1V, or 0.9V.
All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC). Typical values are at T
Current limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, for a 1.0V
Dropout voltage is defined as the input to output voltage differential when the input voltage is set to the nominal output voltage. Also Dropout
