Simple power supply 5V, 0.5A

Simple power supply 5V, 0.5A
The 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
