Allowable ripple voltage
There is no one answer about how much ripple is too much, because that depends on the devices being powered. … All that said, 20 mV ripple on a 3.3 V supply should not cause trouble for an ordinary microcontroller or digital logic. …

Full-wave bridge rectifier with capacitor filter and ripple voltage
current over time is:
dV = A s / F
where:
dV is the voltage change
A the current in Amperes
s the time in seconds
F the capacitance in Farads
This pretty much tells you the peak to peak ripple …
