Is there a KiCad symbol and footprint for the HT7540S?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT7540S?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the HT7540S datasheet?
UMW publishes it: the Datasheet link on this page opens it.
Where can I order the HT7540S?
JLCPCB lists it as part C18057292, with 5,054 in stock; the sellers' links on this page open their listings.
What can replace the HT7540S?
Parts like it in the library: the ME6209A40M3G by MICRONE, the HT7140-1 by MSKSEMI, the MST52L40BTE by MST and the HT7140S by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.
