: Ripple filter for power supply
A large value is required to get an excellent ripple characteristic under the line operation, but it must be made
smaller to shorten the starting time.
The recommended value is 10 F. If made too small the low frequency characteristics will change for the
worse, and too large a capacitance value will increase the rising time when power is applied.
A short emitter resistor on the AC, which prevents an AC signal from feedback from being input.
The closed loop voltage gain is determined by these components in relation to the internal resistance at Pin 3.
