Questions
Is there a KiCad symbol and footprint for the L5987A?
Yes. The symbol is EasyEDA_Cloud:L5985TR and the footprint EasyEDA_Cloud:HSOP-8_L5.0-W4.0-P1.27-LS6.2-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the L5987A?
HSOP-8-EP, with 9 pins. Its footprint is drawn on this page.
Where is the L5987A datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L5987A?
JLCPCB lists it as part C1355509, with 0 in stock; the sellers' links on this page open their listings.
What can replace the L5987A?
Parts like it in the library: the TPS54327DDAR by Texas Instruments, the TPS5432DDAR by Texas Instruments, the TPS54428DDAR by Texas Instruments and the PAM2320BECADJR by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
