Note 7. In low temperature (below 0 ˚C), the capacitance of electrolytic capacitor becomes lower. Therefore,

set higher values when using in low temperature.

Concerning the wiring length between the capacitor and the IC, the shorter the better.

Capacitors with good frequency characteristics such as tantalum capacitors, laminated ceramic

capacitors, and aluminum electrolytic capacitors for switching power supply are recommended for the

external capacitors.
