Rohm Semiconductor has a series of linear voltage regulators called the 78 series. The question has been asked, what is the difference between CP and FP in the manufacturer part numbers? We can provide the answer.
For this series specifically:
CP = through hole package (TO-220CP-3)
FP = surface mount package (TO-252-3)
