Note 6. Use capacitors whose capacitance fluctuation is within ±50 % including fluctuations due to temperature

and tolerance (effective value: 0.5 to 7.05 µF).

Use of capacitors with excellent high-frequency characteristics (such as multilayer ceramic capacitors,

tantalum capacitors, and aluminum electrolytic capacitors for switching power supply) is recommended.

Keep the wiring length between a capacitor and an IC pin as short as possible.
