low noise 5v car psu
Hi guys,
I would like to build a PSU for my MP3 player to use it
in my car.
I would like to get 5V from 14.4V, and remove the ignition noise.
It has to provide about 2 amps max, to drive the project and a
notebook hdd.
Is it possible to build one that won't get hot while not in use,
i mean the PSU turned on with no "consumer" on it?
(for example a 7805 gets very hot while dissipates the difference
betweeen 14V and 5V)
I'm not very familiar with PSUs,
thanks,
Zed
