1 Guaranteed by design and characterization; not production tested.

2 Based on an endpoint calculation using 10 mA and 2 A loads.

3 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 defined as the time from the rising edge of EN to VOUT being at 90% of the 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.

1 The minimum input and output capacitance must be >7.0 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.
