It seems a 8 - Dual Flat No Lead (DFN) package. I do not find anything with that marking codes.
Do you see any manufacturer logo?
What voltages does it use?
 
The input is 5V - on pin number 8, pin number 5 is connected to coil, the GND is only the heat-sink , the output I have no Idea what it should be, no manufacture logo, the bottom has heatsink, the coil is 1R5 (probably 1.5 micro henry)
I guess the voltage out can be anything between 3.3V to 1V, attached is bottom side picture

It's complicated to find that part. I have seen a lot of regulators with the same package but with different marking codes.

Maybe other parts of the circuit give you a clue to find the correct component. It could be that a microprocessor or another IC works with this regulator.
