Notes: 5. 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 V
IN
= 2.0V.
6. At V
IN
< 2.3V, the PSRR performance may be reduced.
7. Test condition for all packages: Device mounted on FR-4 substrate PC board, 1oz copper, with minimum recommended pad layout.
