Sample Printed Circuit Pattern
Description of External Parts
C1, C4
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.
