Is there a KiCad symbol and footprint for the HT7733SA?
Yes. The symbol is EasyEDA_Cloud:HT7733_C259880 and the footprint EasyEDA_Cloud:SOT-23-5_L3.0-W1.7-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 HT7733SA?
SOT-89-3, with 5 pins. Its footprint is drawn on this page.
Where is the HT7733SA datasheet?
Holtek Semicon publishes it: the Datasheet link on this page opens it.
Where can I order the HT7733SA?
JLCPCB lists it as part C259571, with 0 in stock; the sellers' links on this page open their listings.
What can replace the HT7733SA?
Parts like it in the library: the XL1509-3.3 by UMW, the XL1509-3.3E1 by XLSEMI, the TPS613221ADBV by Texas Instruments and the TPS63031DSKR by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the HT7733SA?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
