How about a 5.1 volt zener. that way you will acheive regulation as well www.jameco.com has them for for 12 cents. I know you mentioned not wanting a regulator but the 78L05 low power version of the 5 volt is only 29 cents. I recommend the regulator or the zener, at least that way you will have some regulation rather than taking a chance on overheating the 5V ic's in your project Eddie, kc4awz -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
