The power supply is designed to supply stabilized voltage 5V various digital devices with a current consumption of up to 0.5 A. the Transformer T1 is made on the yoke SLH. The network contains 1650 turns of PEV-1 d=0.1 mm, winding II - 55 turns sew-1 d=0,47. In General for the unit can be powered by a suitable pre-transformer with a capacity of 7 W, providing for the winding II AC voltage 8...10 V at a current of not less than 500 mA.
The control transistor VT2 mounted on an l-shaped dural plate 50x50 and a thickness of 2 mm.
