Questions
Is there a KiCad symbol and footprint for the LR7540-M?
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 LR7540-M?
SOT-89-3, with 3 pins. Its footprint is drawn on this page.
Where is the LR7540-M datasheet?
LR publishes it: the Datasheet link on this page opens it.
Where can I order the LR7540-M?
JLCPCB lists it as part C486078, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LR7540-M?
Parts like it in the library: the ME6209A40PG by MICRONE, the BL8503-40PSM by BL, the ME6210A40PG by MICRONE and the MD52A40PA1 by Shanghai Mingda Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
