Questions

Is there a KiCad symbol and footprint for the L5970D?

Yes. The symbol is EasyEDA_Cloud:L5970D 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 L5970D?

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

Where is the L5970D datasheet?

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

Where can I order the L5970D?

JLCPCB lists it as part C1355778, with 2 in stock; the sellers' links on this page open their listings.

What can replace the L5970D?

Parts like it in the library: the TX4143B by XDS, the AP1534SG by Diodes Incorporated, the MC34063 by HXY MOSFET and the SXL1509-5.0E1 by JSMSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
