tantalum capacitor with low Equivalent Series Resistance
(ESR). If you use a tantalum type capacitor with high ESR
A 1.0 mF tantalum capacitor is the recommended value
It is recommended to use a 2.2 mF or higher tantalum

value of this capacitor, output might be unstable. For a
ceramic type capacitor it is recommended connection
about 1 W resistor in series for the stability of output
voltage. The relation between Output Current of regulator
and ESR of an output capacitor is shown in Figures 32 to
34. Those charts show minimal value of ESR for stable
output voltage in Fast Transient mode. The minimal ESR
of an output ceramic capacitor in Low Power mode is
40 mW for all output voltages. For PCB layout
considerations, place the output capacitor close to the
output pin and keep the leads short as possible.
