I'm wracking my brains here trying to remember how to work out the value
of the smoothing capacitor *before* the voltage regulator for a PSU I'm
building, the parameters are
mains freq=50Hz supply voltage 240vac, transformer winding output 11.9v
The PSU design provides +5 volts via a LM323 - max current pull is 3 Amps
- primary smoothing cap value=???????
any help appreciated
