Notes: 1. Ratings apply to ambient temperature at 25°C

2. The device maintains a stable, regulated output voltage without a load current.

3. Dropout voltage is the voltage difference between the input and the output at which the output voltage

drops 2% below its nominal value. This parameter only applies to output voltages above 1.8V.
