Is there a KiCad symbol and footprint for the HT7722?
Yes. The symbol is EasyEDA_Cloud:HE9116A50NR 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 HT7722?
SOT-89-3, with 3 pins. Its footprint is drawn on this page.
Where is the HT7722 datasheet?
Holtek Semicon publishes it: the Datasheet link on this page opens it.
Where can I order the HT7722?
JLCPCB lists it as part C259537, with 0 in stock; the sellers' links on this page open their listings.
What can replace the HT7722?
Parts like it in the library: the LTC3106IUDC#PBF by Analog Devices and the LC3500CB3TR22 by LEADCHIP. Check their datasheets: a part that fits the footprint may still differ in its ratings.
