ok ok i'm building a voltage reg...erm help?
April 23, 2012
ive decided to build the voltage regulator board but im clueless about the voltages
ill be using a TS 7805 CZ reg , a larger capacitor in front and a smaller one after ... but how do i decide on the capacitor size?
i want a steady 5v supply for my machine and i have a choice of 6 rechargeable AA batteries (7.2v) or 8 AA's (9.6v) ... i'd prefer to use the 7.2v as i could swap it later for some battery packs i have (when i find a way to charge em) but it just makes the 2.0v vdrop... whereas the 9.6v version makes the 2/3 vdrop some peeps say is better...
oh and could you explain how you came to the conclusion as i'm more used to biological fluid logic rather than maths based logic.
