A dripping faucet after the water has been turned off is usually caused by a worn-out or damaged washer or seal in the faucet. This allows water to continue leaking through even when the faucet is closed.
To fix a faucet leak from the spout, you can start by turning off the water supply to the faucet. Next, disassemble the faucet and check for any worn out or damaged parts, such as the O-rings or washers. Replace these parts as needed and reassemble the faucet. Turn the water supply back on and test the faucet to see if the leak has been fixed.

Some faucets use the water pressure to open the seal after it has been released by the handle. It may be that the seal is tight and slow to move after it has been released. One other thing to check, is your water pressure ok at this faucet.
