Chosing the right transistor

In the datasheet of the motor there isn't any voice "stall current", but I think is about 0.2A, because is the only current data on it.
Is a very small and low power motor.

jremington:
Google "arduino motor control" for other examples, but avoid Instructables.

I seen a device called "L9110", Can it work?
