This power supply is very simple in that it derives its power from a USB socket, and allows feeding of the circuits that require 5V, is also present an integrated LM317 that with the values of R1 and R2 chosen provides in output a voltage of 3, 3V (see diagram) The self-resetting fuse F1 protects your PC, the power supply can be switched off by pressing the switch SW1 while the lighting of the PWR LED indicates the presence of voltage. There are two connectors from which to draw the voltages 5 and 3.3V. The USB v2.0 standard specifies a maximum of 500mA at 5V. The fuse on board limits the current note this value.
