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 with the circuit as shown above, and if the noise level is 40
μV or less
than 40
μV, the ESR values are plotted as stable area. Upper limit is described in the next four graphs, or ESR vs.
Output Current. (Hatched area is the stable area.)
