5v to 3.5v

Hello

i need a 5V to 3.5V regulator, but where do i buy one?
or if anyone has a schematic, how do i build one?
 

3.5v regulator

Use a step down regulator with adjustable output. You can get these regulators from National Semiconductor, Texas Instruments, Linear Technology, etc.
 

3.5v to 5v

How many ma ???

I use Micrel 2920 3.3v ldo's (400 ma)

regulator 3.5v out

You may use the LM2575-3.3. It is a switching regulator
 

lm3985

id like to be on the safe side, and 500mA is the maximum it'll have to take

EDIT: and it should be able to take from 4.40V to 5.25V and give 3.00V to 3.60V, with a maximum I of 500mA
 

5v a 3.5v

Hi.
Cannot understand the habit of doing things the hard way.

Just connect two 1N4001 silicon diodes in series to your 5V source and you will get 3.5V
