(*1) Make sure that output capacitors is 10μF or more and ESR 10Ω or less in total, in which voltage and temperature fluctuation and unit differences are taken
into consideration. Moreover, high frequency characteristics of electrolytic capacitor should be sufficient.
Furthermore, the values listed above do not guarantee stabilization during the over current protection operations of the regulator, so oscillation may occur
during an over current protection operation.
