Questions
Is there a KiCad symbol and footprint for the HT7218?
Yes. The symbol is Pinmap_Generic:Regulator_Linear_1IN_2GND_3EN_4NC_5OUT and the footprint EasyEDA_Cloud:SOT-23-5_L2.9-W1.6-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 HT7218?
SOT-89-3, with 5 pins. Its footprint is drawn on this page.
Where is the HT7218 datasheet?
Holtek Semicon publishes it: the Datasheet link on this page opens it.
Where can I order the HT7218?
JLCPCB lists it as part C259603, with 2,886 in stock; the sellers' links on this page open their listings.
What can replace the HT7218?
Parts like it in the library: the HT7818 by Holtek Semicon, the AP2112K-1.8TRG1 by Diodes Incorporated, the ME6211C18M5G-N by MICRONE and the ETA5055V180DD1E by etasolution. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the HT7218?
2 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
