Is there a KiCad symbol and footprint for the HT7233?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3EN_4NC_5OUT and the footprint EasyEDA_Pro:sot-23-5_l3.0-w1.7-p0.95-ls2.8-br, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT7233?
SOT-23, with 5 pins. Its footprint is drawn on this page.
Where is the HT7233 datasheet?
HOLTEK publishes it: the Datasheet link on this page opens it.
Where can I order the HT7233?
JLCPCB lists it as part C77938, with 5,682 in stock; the sellers' links on this page open their listings.
What can replace the HT7233?
Parts like it in the library: the AMS1117-3.3 by Advanced Monolithic Systems, the AMS1117-3.3 by UMW, the ME6211C33M5G-N by MICRONE and the SPX3819M5-L-3-3/TR by MaxLinear. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the HT7233?
4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
