Is there a KiCad symbol and footprint for the HT7533?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1GND_2IN_3OUT 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?
SOT-89, with 3 pins. Its footprint is drawn on this page.
Where is the HT7533 datasheet?
KEXIN publishes it: the Datasheet link on this page opens it.
Where can I order the HT7533?
JLCPCB lists it as part C499633, with 7,564 in stock; the sellers' links on this page open their listings.
What can replace the HT7533?
Parts like it in the library: the AMS1117-3.3S by UMW, the L78L33ACU by STMicroelectronics, the HT7533-1 by UMW and the AMS1117-3.3 by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the HT7533?
12 boards in 11 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
