Minimum output load current is 500 μA.
Accuracy when VOUT is connected directly to ADJ. When VOUT voltage is set by external feedback resistors, absolute accuracy in adjust mode depends on the tolerances
of the resistors used.
Based on an endpoint calculation using 10 mA and 2 A loads. See Figure 6 for typical load regulation performance.
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 1.6 V.
Start-up time is defined as the time between the rising edge of EN to V OUT being at 95% of its nominal value.
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.

The minimum input and output capacitance should be greater than 3.3 μF over the full range of operating conditions. The full range of operating conditions in the
application must be considered during capacitor selection to ensure that the minimum capacitance specification is met. X7R and X5R type capacitors are recommended;
Y5V and Z5U capacitors are not recommended for use with this LDO.
