Are these two circuits equal?


Recommended Posts


Dear audioguru

when you are to power an MCU based or a sensitive device from an iginition power supply, i.e. when connecting your circuit to a Car, because of high transient voltage (upto 60v) you can not just use
7805 and some capacitors;
if you search between the car CD players you can always see an inductor around 800uH before the regulator and some caps around it; without this inductor, you will have crash!

now if you are conviced, can you tell me Do those two circuits (I attached) differs?
