100 µF Feedback capacitor Decreasing the capacitance value lowers the low frequency response. 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 temperature characteristic. The use of an electrolytic capacitor may cause oscillation to occur at low temperatures. Power capacitor Decreasing the capacitance value causes ripple to occur. Locating at a distance from the IC or removing this capacitor may cause oscillation to occur. Ripple filter capacitor Decreasing the capacitance value excessively or removing this capacitor causes ripple to occur. However, increasing the capacitance value does not always cause ripple to be reduced. Decreasing the capacitance value makes the starting time earlier. Input bias resistor Determines the bias (bias of GND potential) to be applied to the input pin and the input impedance. Not required if variable resistors are used. Resistor connected in series with oscillation blocking capacitor. Prevents phase shift attributable to the oscillation blocking capacitor so that oscillation is hard to occur.
