I've been looking over how to find power dissipation for voltage regulators, op-amps, comparators, logic gates, and amongst other things.(adsbygoogle = window.adsbygoogle || []).push({});

Ive looked at some resources and I'm not getting what each variable means.

From what I understood so far I've seen

PDstatic = Vcc*Icc where Vcc and Icc are the supply voltage and currents found in the datasheet

Then for voltage regulators since there isnt a source voltage I used

PDstatic= (Vin-Vout)*Io where you subtract input voltage and output voltage and find the load current from the schematic.

Then for logic gates I use

(I^2)Rdon , where Rdon is the gate source resistance found in the datasheet.

(1/2)*C*V^2, where C is the mos capacitnce also found in the datasheet

ARE ANY OF THESE CORRECT?! There are just too many sources and I just don't know a general way of finding the static PD.

I'll ask about dynamic power dissipation after I get this
