Happy Thanksgiving Pic guys. I have a project using a PIC16F1847 and it is a simple Led tracer application.It will be mounted in a truck and will be powered by the 12volt system in the truck. My choice is the 7805 linear voltage regulator but My friend told me this was not a good choice for automotive applications. I found the TI Lm2940 low drop out voltage regulator. I was going to use this but I noticed that Digi Key states this device is out dated and not to use in it in new designs. So does anyone out there know of a newer low drop out 5 volt regulator for this purpose? Any help would be appreciated Thank You Michael Johnston --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
