Guaranteed by characterization but not production tested.
Based on an endpoint calculation using 100 mA and 5 A loads.

Dropout voltage is defined as the input-to-output voltage differential when the input voltage is set to the nominal output voltage, which applies only for output
voltages above 1.1 V.
4
Start-up time is the time from the rising edge of V
EN
to V
OUT
being at 90% of its nominal value.
5
Current-limit threshold is 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 must be >14.5 µF over the full range of the operating conditions. Consider the full range of the operating conditions in
the application during device 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 any LDO.
