Time taken for capacitor Ccp 2 (charging capacitor) to fill up Ccp 1 (storing capacitor) to V
The internal IC cannot drive the gates correctly until the voltage of Ccp 1 reaches V
Basically, the larger the Ccp 1 capacitance, the smaller the voltage fluctuation, though the initial charge
The smaller the Ccp 1 capacitance, the shorter the initial charge-up time but the voltage fluctuation is
Depending on the combination of capacitors (especially with small capacitance), voltage may not be
Thus, use the capacitors under the capacitor combination conditions (Ccp 1 = 0.22 µF, Ccp 2 = 0.02 µF)
