Caution of Stability Area

If the Aluminum electrolytic capacitor is used, it should be kept CKA ≥ 2.2 µF.

When using plural different types of capacitors, each capacitor is needed to be stable independently.

When designing a circuit, take the characteristic variation among devices into consideration, so that the designed

circuit has an enough characteristic margin supporting the standard specifications described above.
