Questions
Is there a KiCad symbol and footprint for the L5981?
Yes. The symbol is EasyEDA_Cloud:L5985TR and the footprint EasyEDA_Cloud:DFN-8_L3.0-W3.0-P0.50-BL-EP, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the L5981?
VFQFPN-8(3x3), with 9 pins. Its footprint is drawn on this page.
Where is the L5981 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the L5981?
JLCPCB lists it as part C2071200, with 0 in stock; the sellers' links on this page open their listings.
What can replace the L5981?
Parts like it in the library: the LTC3624IDD-2#PBF by Analog Devices, the LT3505EDD#TRPBF by Analog Devices, the LT3473EDD#PBF by Analog Devices and the LTC3624IDD-5#PBF by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
