Questions
Is there a KiCad symbol and footprint for the LR7140-T?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2OUT_3IN and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LR7140-T?
SOT-23-3, with 3 pins. Its footprint is drawn on this page.
Where is the LR7140-T datasheet?
LR publishes it: the Datasheet link on this page opens it.
Where can I order the LR7140-T?
JLCPCB lists it as part C914129, with 1,108 in stock; the sellers' links on this page open their listings.
What can replace the LR7140-T?
Parts like it in the library: the AP2210N-4.0TRG1 by Diodes Incorporated, the MD5340 by Shanghai Mingda Microelectronics, the MD7540 by Shanghai Mingda Microelectronics and the BL8503-40PRM by BL. Check their datasheets: a part that fits the footprint may still differ in its ratings.
