Hey everyone. I am kind of new to making physical electronic circuits. Currently I am trying to build a simple power supply.
Input = 230VAC 50HZ
Output Loads --
Load 1: 12V 12mA
Load 2: 12V 1.2A
Load 3: 3.3V 80mA.
Now I designed a circuit using multisim using a LM7812CT regulator that has a rating of 12Vout 1A. Now I am confused. If the rating of this regulator is 1A, how is it able to power 1.292A loads all connected together? Is it possible that it will run in the simulation but will not work when i actually build it?
Also the step down transformer I am using is 230V to 15V step down with 1A rating. Maybe i am unaware of some concept?
Also, If i add a relay with rating 12V 1A, will i need to increase the transformer to a higher rating? maybe a 15V 3A? But then again if the loads together pull 2.3A from a regulator that has a rating of 1A, won't the regulator burn out?
These questions may seem very stupid, but i am starting out new into building electronics and I am very keen to learn and make circuits. Any help or advise is appreciated.
Thank you.
