output voltage is defined as the current that causes the output voltage to drop to 90% of 3.0 V, or 2.7 V.
application must be considered 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.
Based on an end-point calculation using 1 mA and 100 mA loads. See Figure 6 for typical load regulation performance for loads less than 1 mA.
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
Start-up time is defined as the time between the rising edge of EN to VOUT being at 90% 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 3.0 V
The minimum input and output capacitance should be greater than 0.70 μF over the full range of operating conditions. The full range of operating conditions in the
