Hellow every body,
I need your help on something I need to build a power supply of 220/12 volt regulated with 5 amperes,
I have located some circuits here and there but they all need large heat sinks somethink like 10*200*100 mm aluminum, or can even need a fan for that IC regulator and pass transistors, so does any have a diagram that needs less heat sink spaces,
my real problem is in my country Jordan there aren't any 5A 12 V regulator ICs they use only the known 70812 with pass transistors ?
can any one help me build this power supply with this IC 78012 without having to use so much space in heat sinks?
thank you all
