rx5 said:Hi all!
im gonna use a 7805 as a 5volt reg... but is not efficient enough?? gonna use it in low current apps.... (<5mA at most)....
ive heard of micropower or microwatt regulators(+5V and 3.3V) i just forgot the specific part number though... im having a hard time sourcing those.... but i could easily get 7805 or 78L05 here....
so is it possible to create one out of discreet parts? (transistors,resistors, diode etc etc) ??
any help is really apreciated
I think datasheet usually states the efficiency at rated load. Pls correct me if I'm wrong.banh said:can i ask,
based on what condition do we rate the efficiency of the regulator?
is it the current requirement of the circuit?
