Questions

Is there a KiCad symbol and footprint for the HT7333?

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 HT7333?

SOT-89, with 3 pins. Its footprint is drawn on this page.

Where is the HT7333 datasheet?

Minos publishes it: the Datasheet link on this page opens it.

Where can I order the HT7333?

JLCPCB lists it as part C19272223, with 8,791 in stock; the sellers' links on this page open their listings.

What can replace the HT7333?

Parts like it in the library: the AMS1117-3.3S by UMW, the AMS1117-3.3 by GOODWORK, the CJA1117B-3.3 by Jiangsu Changjing Electronics Technology (CJ) and the AZ1117CR-3.3TRG1 by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the HT7333?

24 boards in 23 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
