Increasing the capacitance value makes the starting time later. Input short capacitor Reduces the high frequency noise when the input impedance is increased. Not required when the input impedance is decreased. Output capacitor Decreasing the capacitance value causes insufficient power at low frequencies. Oscillation blocking capacitor Decreasing the capacitance value causes oscillation to occur easily. Use a polyester film capacitor that is good in high frequency response and te |
