hi,
i have a power supply unit, the one from a laptop.its a 19v 2.3A dc output. im planning to use it to power my fans in my desktop.the reason i want to use it this power supply unit is because i dont want to burden my desktop's power unit. i've got three fans having 0.8A+0.15+0.20=1.15A in total.all 12V fans.
my problem is i dont have any idea on how to make a circuit using the 7812 IC chip.can anyone guide me please?
