Brian,
14.5-14.6 is a normal automotive charge voltage if the vehicle battery is nearly fully charged.
If I drop say 0.5v due to wiring losses and 1v in a LDO current regulator that gives a max charge voltage 13V which should hopefully get the battery to 90% charge which will be enough.
I...
Can any-one recommend a 3 pin current regulator with low voltage drop between input and output voltages?
This is to charge a car lead acid battery from a cigarette lighter as fast as possible so would like to use the 20A available from the cigarette lighter.
I have a LM317 however this has...
