Here are two simple AC-DC power supply circuits, one without a filter and one with: Filter Plug Vunfiltered Vfiltered Plug. Use an ATX PC power supply as a 5V, 3. Switching,Linear,Regulated,Custom,HV,Redundant,1U. combined feedback for 5v and 12v outputs. Then have an AND gate that if it sees 5V from both the USB power (before the buffer chip) and 5V from the ATX power supply, 1 and 1 = 1 (and chip selects are typically active low meaning that a '1' will turn OFF the USB supply). This project details the design of a very low dropout adjustable power supply. When we use a Cheap MP3 Player which use only one 1. 5V batteries in series that act as a 3V source. Using two regulators helps spread out the power dissipation between the two devices so a heatsink isn't needed. Its circuit is shown below. Whatever 5v power supply styles you want, can be easily bought here. Its a must have product for experimenters those have to test/prototype electronic circuits on breadboard or perforated/veroboards. You mention that your relay's coil is around 300 ohms, so if you put a 10-15 ohm resistor in series with the power supply for the circuit - including the power to the relay - will drop the voltage only few percent under that load. The LM338 has a. Adafruit industries unique fun diy electronics and kits 5v 2a 2000ma switching power supply ul listed id. Domotique 34. Pi Power from Geppetto Electronics is a 6-15 volt switching supply (with a 2.
