We are using on the board an
az1117 regulator to some kind of toy.
The toy works with
3.7v, hence we use this regulator.
The question- when the processor sleep, the output current will be 5uA, but I guess a
9V battery as an input with this regulator will be a bottle neck in terms of quiescent current.
- How do you calculate from the data sheet, what would be the quiescent current for
9V or 5Vinputs? it says on the data sheet that its 5mA for
VIN=VOUT+1.25V. What about
- Is there anything you can do to eliminate this bottle neck? the only option is to disable it but then there will be no voltage to the sleeping processor.
