I'm a designing a circuit that I'll prototype soon.
I'm curious about how should I determine my power budget for the circuit? Could you guys please suggest me how to do it? Should I calculate each power rail Watt and sum it? Do you have any suggestions for 'excel' table for this?
I would like to hear suggestions please or to know how the pros do it.
I assume that power budget estimation is important because according to this estimation I choose, for example, a voltage regulator. according to the power estimation (W) of rail - the power shouldn't deviate the power dissipation of the voltage regulator - Am I right?
Thank you very much, also forgive me about the newbish question :)
