You mean just use the buck regulator directly? Yes, you can if you just want to run a PIC. I used an additional LDO for better accuracy, less noise, and better transient response. I figured some applications will use the PIC A/Ds, and with a good clean and accurate 5V supply you can get away without a separate A/D reference voltage much of the time. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
