Simple power supply 5V, 0.5A

5v power supply 0.5A circuitThe power supply is designed to supply a stabilized 5V various digital devices with current consumption up to 0.5 A. The transformer T1 is made on the magnetic core SHL20H32. The network contains 1650 turns of PEV-1 d = 0,1 mm, coil II – 55 turns of PEV-1 d = 0,47. In general, for the power supply can use a suitable transformer ready 7W, which provides for winding II AC 8 … 10 V at a current of 500 mA. Regulating transistor VT2 is mounted on the L-shaped dural plate 50×50 and 2 mm thick.

Power supply is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.
