How does a smoothing capacitor work?
Voltage ripple can be smoothed by adding parallel capacitors across the load in a rectifier circuit. The degree of smoothness increases when the capacitance increases. Is a smoothing capacitor a filter? Ripple current peak-to-peak into the −5V output capacitor is approximately equal to twice the negative load current.
