    I lost my Adpater and at all Egypt there’s No adapter like that

    , I know how execute circuts if anyone brief me in circuts of Adpter I will be greatful

    the adpater input 220v or 110 it doesn’t matter but the output is 5V 2.5A

    thank for everyone intend to help

    you need a step down transromer for 2.5A….

    and refer to link:

    and atke T0-3 packaging of 7805 what might provide you the higher o/p current at constant voltage

    7805 is only 1.5A according to datasheet so if you need 2.5A then you may use LM350/LM317 because it is 3A adjustable voltage regulator..

    yes romel you are correct but there are some of that 7805 avialable which can provide higher current…

    using LM317 is also a good option

    i was just thinging about it…. can we use zener to make some constant supply sorces?

    yes.. that is use commonly in some power supply to limit voltage accross the line.. but i dont know what’s the difference of other regulator.. i think the regulation method is not the same when using zener diode only
