I would be cautious about using a switching regulator without also providing proper EMI/RFI suppression. Without it you may cause _lots_ of grief for your site neighbors. The switching solution is much more efficient, but at a higher complexity / construction cost to do correctly and quietly. Ed Yoho W6YJ
