Accuracy when OUT is connected directly to ADJ. When OUT voltage is set by external feedback resistors, absolute accuracy in adjust mode depends on the tolerances
of resistors used.

Based on an end-point calculation using 10 mA and 300 mA loads. See Figure 10 for typical load regulation performance for loads less than 10 mA.
3
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 for output
voltages above 2.5 V.
4
Start-up time is defined as the time between the rising edge of EN to OUT being at 95% of its nominal value.
5
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 1.0 V
output voltage is defined as the current that causes the output voltage to drop to 90% of 1.0 V, or 0.9 V.
