5 volts from the Mains by LM2595T-5.0| Circuit Project

Sometimes we would like to hide certain equipment to prevent cluttering up our living room or any interior in general. A number of devices lend themselves to be built into a wall adapter. Think of a remote-control extender, for example.All these devices need a power supply and we would prefer to use the mains so that no external connections are required for the power supply.The power supply in this article is intended for exactly these situations, namely converting the mains voltage to a 5-V power supply voltage. The accompanying PCB fits exactly in a round wall socket enclosure.
