0.8V to 3.3V Output type: COUT
=4.7μF (Kyocera CM105X5R475M06AB)
5.0V Output type
: COUT
=4.7μF (Kyocera CT21X5R475K06AB)
As an output capacitor for this IC, Ceramic capacitor is recommendable. However, other low ESR type
capacitor can be used with this IC.
For your reference, noise level is tested, and if the noise level is 40
μV or less than 40μV, the ESR values are
plotted as stable area. Upper limit is described in the next five graphs, or ESR vs. Output Current. (Hatched area
is the stable area.)
