Hello jing chen,
Thank you for patiently waiting. The part LT3045IMSE#PBF exactly has a pad-pad clearance of 6.69mil because it was created following IPC standards that's why the SMD pads are bigger. Would you like us to recreate the part following the manufacturers recommendation?
I really appreciated for your response, i am new to Altium and PCB design, currently working on my first board and didn't realize some drc rules don't apply to pads separations within same component.
My mistake, i apologize.
