6V to 5V

[skimask]

hi,
i need a way to take 6V and drop it down to 5V in a 'clean' way, the output voltage of 5V
must stay pretty constant. I have a motor running off the 6V and a receiver (from a radio control) that needs a constant 5V
any help would be great, thx

I would think that any receiver could tolerate running from the same supply as your 'motor', with the above mentioned 'cleaning' of the power supply itself from the noise caused by the motor.

What I think would worry me would be the voltage droop caused by the motor starting up causing the overall voltage to drop too low to support safe operation of the receiver.

cuz the problem is that i have 2 cordless 18V drills running off of a 6V 42 amp per hour battery with a 12V 38 amp per hour battery. i also have 2 little 12V motors (draws less then an amp) hooked out to the 12V. The reciever needs a constant 5V , i could use a 7805 regulator with the 12V, but i would like to use the 6V for the reciever's 5V.

These are nice if you do not mind the extra parts.

If you don't need much current, add a 1K resistor in series and a parallel zener diode.
