プロトタイプ PCB にオンボード レギュレータまたは外部電源を使用して電力を供給するのは良い考えですか?? 任意のヒント?

はい, you can lay out an external power section with a nice meaty capacitor. It saves picking a VReg. Tips are as follows.

• Over-spec the regulator for external power, so you don’t have to worry about the power requirements changing.
• If you are involving high voltages, keeping it away from the main board is best. It is quite common for the power supply portion to be on a separate board anyway – makes for a more modular system that is easier to design or redesign.
