6v to 5v?

What should I use to reduce the voltage from 6v to 5v?
simple resistor or some kind of regulator?

Try the 7805 regulator.
 

6v to 5v?

I understood that the min input for the 7805 is 7v so it won't work
 

6v to 5v?

A LDO will help i think.

By the way, want is the current requirement
 

6v to 5v?

I need 5v to make pic16f84a work properly

I said try maybe it work.
Now it seems to be clear.

I have an Idea. Use two Diode in serie (1n4007 for exemple). Since each one drops 0.7V y'oull get 4.6V. The PIC will operate correctly since, as far as I remember the 16f84 require a voltage supply ranging from 3.7 to 5 V.

I hope I helped.

Cheers,
Advares.
 

Re: 6v to 5v?

simply use a Diode. the voltage drop across the diode will be around 0.65 to 0.7

Yes.. i was too about to sugest the same point sugested by "hameeds01" The diode will drop the 6 volts to 5.4 volts which can be used to drive PIC directly .But ensure that in further use the voltage will go down below 5.4 and not rise above that (May be during charging if the 6 volt source is a battery)
Or as your requirement is only to drive a PIC micro, you may use a resistor + Zener diode combination to get 5.1V which will be safer compared to the later sugession. Cheers

How did I forget that :D?

Sorry..i too forgot one more thing..PIC16F84A's both Industrial and commercial versions work from 2.0volts to 5.5volts. Cheers..:D:D
