I would like to connect to Regulator EN pin, when excess current is drawn to shutdown regulator.
Some schematics is found but seems to be not suitable.
The flow of Power supply is Bridge Rectifier -> Conditioning Capacitor -> (7V/7.5A) -> Linear LDO Regulator. I'd like to insert detection circuit between capacitor and Regulator,if possible, in parellel for low voltage drop.
Then 5V logic overcurrent detection line would be connected to EN pin of regulator.

Could you advise me the above overcurrent protection circuit?

Thanking you in advance
