never said it was but that was the formula i was told is there another way to work it out ?
btw what r the output specifications of this thing

This doesnt make any sense to me whatsoever. The units arent even right.

Eh...not always you have to work it out (unless its that important). Most of the time if you look at your regulator datasheet it will give you a a basic schematic hook up and tell you what kind of capacitor you need. Just make sure the voltage rating is high enough.

err rectification on the formula i posted the other day. i have just come across my old note book and found it again and it is NOT 20000/(V X I) but 20000/(V/I) and do not ask why it is not 20000/V/I because i have never tried to verify it is the same but common sense tells me it is :lol

It is still not a capacitance and it has no basis at all. I'm sorry, but unless you can show us by derivation, it is simply wrong. If that's what you have in your notes, scratch it out! :-) Originally Posted by Thunderchild

wel ys it ould be wrong i mean i read it in a magazine and allhould know that sometimes hey ome out with some weird stuff theor wise ut if my formul i rong then i too now ask: how do you calculate the capacitance needed.
btw the result of myformula should give uF (miro farads) directly.0
