Questions

Is there a KiCad symbol and footprint for the HT7544-2?

Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT_4NC_5NC and the footprint EasyEDA_Cloud:SOT-23-5_L2.9-W1.6-P0.95-LS2.8-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the HT7544-2?

SOT-89-3, with 5 pins. Its footprint is drawn on this page.

Where is the HT7544-2 datasheet?

Holtek Semicon publishes it: the Datasheet link on this page opens it.

Where can I order the HT7544-2?

JLCPCB lists it as part C259502, with 16 in stock; the sellers' links on this page open their listings.

What can replace the HT7544-2?

Parts like it in the library: the HT7544-1 by UMW, the HT7144-1 by MSKSEMI, the H7544-1 by Shanghai Siproin Microelectronics and the HE2021A44HMR by HEERMICR. Check their datasheets: a part that fits the footprint may still differ in its ratings.
