What simulator are you using? Where did you get the model for the ACS712 hall effect current amplifier? Does the model have output clamping to simulate the common mode +5 supply?

I presume it is a result of translation error, but you get regulated DC from a 7805.

Make sure your circuit image is in JPEG format, and it should post correctly.
