I was wondering about how to interface a "SuperCap 5.5v 1F" to a circuit :?:
I mean if i just put it directly on my 7805 it will probably destroy it on power on. And what is the advantage/disadvantage vs. a lithium batt :?:
If i just want to "back up" a RTC + Ram , does ine use a diode to prevent it ro power the whole circuit , what about the voltage drop across the diode :?:
Does anyone have some tips and maybe a link to a schematic ???
Ohh is 1.25$ for a 1F Cap , a fair price ???
