Use one battery to build 2 circuits

[Ginnyyk]

Hi,

I would like to use one rechargeable sealed lead-acid battery to supply 2 circuits. One circuit needs 7.2V and the other circuit needs 5V with about 3.5A current. However, I don't know how to regulate two circuits at the same time. Please suggest.

Thank you.

because u need big values currents, its better 2 use 2 different separate circuits, directly from the source (the battery).
personally I ll option for linear stabs because u want like me to stay aside from coils and trafos and a power darlington still does the job
