Hi team.

Thanks for your always support.

We want to downsizing capacitor C1~4(0.1uF).

However Data sheet wrote only 0.1uF.

How can it tolerate capacity width at C1~4 ?

We want the max and min limit capacitance.

Sincerely.

Kengo.

Hello Kengo-san,

The values in the datasheet are our recommended values to provide higher-voltage positive and negative rails with minimal ripple. Other capacitance values can work as well, though. To get a better idea of the tradeoffs involved with different capacitance values, you can reference this blog:

Please let us know if you have further questions.
