I've built my first project with the SX chip. It works fine when it is powered by a 9V battery, but I need to install it in a device where a regulated 12V power supply will provide the juice. When I try to power this project from a 12V regulated power supply, it  won't run. It is getting 5V (+/- 5 mV) to the Vdd pin in all cases. I've even tried replacing the voltage regulator hoping that might have been the problem. Any ideas?
