Questions

Is there a KiCad symbol and footprint for the CJ7550S?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT and the footprint Package_TO_SOT_SMD:SOT-89-3, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the CJ7550S?

SOT-89-3L, with 3 pins. Its footprint is drawn on this page.

Where is the CJ7550S datasheet?

Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.

Where can I order the CJ7550S?

JLCPCB lists it as part C2829418, with 3,474 in stock; the sellers' links on this page open their listings.

What can replace the CJ7550S?

Parts like it in the library: the 78L05-300 by UMW, the AMS1117-5.0V by MSKSEMI, the ME6210A50PG by MICRONE and the AMS1117-5.0 by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
