Hey guys, so I basically need a voltage regulator that can output about 3.75V. I have a 3.3V and 5V voltage regulator http://www.sparkfun.com/products/526
as well as a few capacitors. I am inputting voltage with a 7.4V LiPo battery so I basically need to step that down to around 3.75V although I assume 3.3V would be ok. I tried to solder something together using a L4940V5 and two capacitors like the attached image but it did not work very well because the voltage was not constant and I just need some help to make something that works well and is relatively simple. Essentially I need something like this: http://www.dimensionengineering.com/AnyVoltMicro.htm
but I don't want to spend the $20 because I already have some components and I sort of need to make this by tomorrow.
