Questions

Is there a KiCad symbol and footprint for the L4938E?

Yes. The symbol is EasyEDA_Cloud:L4938E and the footprint Package_DIP:DIP-16_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the L4938E?

DIP-16, with 16 pins. Its footprint is drawn on this page.

Where is the L4938E datasheet?

STMicroelectronics publishes it: the Datasheet link on this page opens it.

Where can I order the L4938E?

JLCPCB lists it as part C7295042, with 0 in stock; the sellers' links on this page open their listings.

What can replace the L4938E?

Parts like it in the library: the LP2953IN by Texas Instruments, the LP2960IN-5.0 by Texas Instruments, the U3525L-D16-T by UTC and the MC33363P by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
