All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC).
This is the input current into VIN3, which is not delivered to the output load.
Based on an endpoint calculation using 1 mA and 300 mA loads.
Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. This applies only to output voltages
above 1.7 V.
Current-limit threshold is defined as the current at which the output voltage drops to 90% of the specified typical value. For example, the current limit for a 3.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 3.0 V or 2.7 V.
