Both minimum capacitance and maximum ESR requirements
must be met. In order to get the low ESR, a capacitance value
of two to three times greater than the required minimum may
be necessary.
The equation for output ripple in continuous current mode is:

The equations for capacitive and resistive components of the
ripple in pulse-skipping mode are:

Lower Voltage Input
The application circuit shown here can be easily modified to
work with 5.5-V to 12-V input voltages. Oscillation frequency
should be set at 200 kHz and increase the output capacitance
to 660 F on the 5-V output to maintain stable performance up
to 2 A of load current. Operation on the 3.3-V supply will not be
affected by this reduced input voltage.
