Generally speaking, LDOs have low quiescent current (e.g. LP2992 at 65uA with no load) there are thousands of varieties so I can't be more specific. -- Martin K. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
