Hello everyone.I have an obstacle detection sensor whose output voltage is 0.72V when obstacle is detected and it is 11V when obstacle is not detected.Now I want to convert this output into 0V to 5V range so as to drive controller input pin. I am thinking of using 7805 for the same.Following are the problems I am facing-
1- If obstacle's presence and absence changes rapidly/abruptly,then can 7805 regulator provide such fast and sharp response? (Is there any delay in its op?)
2-Maximum controller input current is 30mA. So, is it fine to put a resistor in series with output of 7805 to limit current?
