Is there a KiCad symbol and footprint for the HT7533-1?
Yes. The symbol is EasyEDA_Cloud:TL431SI 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 HT7533-1?
SOT-89, with 3 pins. Its footprint is drawn on this page.
Where is the HT7533-1 datasheet?
UMW publishes it: the Datasheet link on this page opens it.
Where can I order the HT7533-1?
JLCPCB lists it as part C347186, with 309,004 in stock; the sellers' links on this page open their listings.
What can replace the HT7533-1?
Parts like it in the library: the AMS1117-3.3S by UMW, the L78L33ACU by STMicroelectronics, the AMS1117-3.3 by GOODWORK and the CJA1117B-3.3 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
