How to convert a DC locomotive to a DCC locomotive?

I need to convert 12v dc to around7.5v dc?

  • i have a 12v battey in dc. but i wan 7.5v dc how?

  • Answer:

    U need a regulator IC. 3 terminals, avail in preset and "any" lower voltage. Can't remember if 7.5 is a std range, but there will be something near it which will prob do. heat dissipation of regulator MUST be adequate, & the device powerful enough to easily handle the load. Most have overload protection built in, but not all. They DO get hot!!! Many also include overheat protection.
