Notes:

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 input voltages above minimum VIN = 2.0V.

4. At VIN < 2.3V, the PSRR performance may be reduced.

5. Test condition for all packages: Device mounted on FR-4 substrate PC board, 1oz copper, with minimum recommended pad layout.
