1 Based on an endpoint calculation using 100 μA and 200 mA loads. See Figure 7 for typical load regulation performance for loads less than 1 mA.
2 Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage. Dropout applies only for output
voltages above 2.7 V.
3 Start-up time is defined as the time between the rising edge of EN to OUT being at 90% of the nominal value.
4 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 5.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 5.0 V or 4.5 V.
