3. The Attempt at a Solution [/B]
Currently working on the question relating to the ground current on the voltage regulator, 7805 (data sheet included below)
I am very much unsure what to calculate here
I'm assuming the current to ground is the input current - output current
However, I don't know how to calculate the input current
Perhaps do I assume there is an PCB track impedance of 0.1 ohm and 0.2uH (from previous questions)? And take the magnitude of the current?
There is no specification in the LPC1768 for the max current the Vin pin draws. However I found the mbed can produce 400 mA of current on the GPIO, so perhaps I can use that for output current of the regulator.
Does this seem like the right approach?UPDATE: Is this what the quiescent current is?
