Note If the use of an electrolytic capacitor at low temperature is likely, set the capacitance with sufficient

margin, because the capacitance of an electrolytic capacitor is smaller at lower temperatures (0

°C or

lower). Care must be taken to minimize the wiring length between the capacitor and this IC. Using

capacitors of excellent high frequency characteristics (such as tantalum, multi-layer ceramic capacitors,

and aluminum electrolytic capacitors for switching power supplies) is highly recommended.
