Capacitor
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
μ
V or less than
40
μ
V, 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.)
