mdaien Posted March 6, 2007 Report Share Posted March 6, 2007 Hello friends,Initially I have to convert the 24V signal to 5V which I did using voltage divider circuit but now the thing is my input signal level is not decided it may vary from 15V to 24V so the question is how can I maintain 5V.My input is varying from 15V to 24V but I required 5V output.. how can I do this??????????/ ;D Quote Link to comment Share on other sites More sharing options...
jgeidl Posted March 6, 2007 Report Share Posted March 6, 2007 Try Googling 7805 voltage regulator. This device with a few caps will control the output. There are about a million circuits out there using it as it is very common.Jim Quote Link to comment Share on other sites More sharing options...
