Fig.12-2 and Fig.12-3 show the stable operation area of
output current and the equivalent series resistance (ESR)
with a ceramic capacitor of 0.68F. ESR of the output
capacitor must be in the stable operation area. Please
select the best output capacitor according to the voltage
and current used. The stability of the regulator improves
as the value of the output side capacitor increases (the
stable operation area extends.) Please use as large a value
capacitor as is practical.

Generally, a ceramic capacitor has both a temperature
characteristic and a voltage characteristic. Please consider
both characteristics when selecting the part. The B curves
are the recommended characteristics.
