      Regulators for battery locos

      I'm just about to create my second battery-powered r/c device [photos will be forthcoming when I collect all the pieces.] It will be DSM2 compatible using a cheap recvr I picked up with 4 LiIon 18650 batteries and an ESC from Tony at RCS.  It occurred to me that I shouldn't be powering the recvr (4.5-6V) from the LiIon battery pack (12-16V.)

      I think my previous conversion does just that.  It is still working, so maybe I tapped the batteries so it isn't feeding the full voltage.  I will have to take it apart and check.

       

      So I believe I need a regulator?  I think Accucraft puts them on the coaches to create a constant 5V.  I see plenty of regulator ICs on the web, but not a lot of curcuit diagrams.  I believe I need a few other components to set the voltage - is there a small device (pcb) that incororates everything?
      Advice requested, please, preferably with pictures.

      Ah - the panic is over.  I emailed Tony who reminded me the ESC has a regulated 5V output for the RX.  That's what my tram is currently using.

      Which is not to say I don't need the regulator, but not for this project.
