Questions

Is there a KiCad symbol and footprint for the LD7552BPS?

Yes. The symbol is EasyEDA_Cloud:LD7552BPS and the footprint Package_SO:SOP-8_3.76x4.96mm_P1.27mm, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the LD7552BPS?

SOP-8, with 8 pins. Its footprint is drawn on this page.

Where is the LD7552BPS datasheet?

Leadtrend Tech publishes it: the Datasheet link on this page opens it.

Where can I order the LD7552BPS?

JLCPCB lists it as part C38767, with 386 in stock; the sellers' links on this page open their listings.

What can replace the LD7552BPS?

Parts like it in the library: the SDH8302STR by Hangzhou Silan Microelectronics, the DK106 by DK, the DK501 by Shenzhen DongKe Semicon and the DK912 by Shenzhen DongKe Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
