Is there a KiCad symbol and footprint for the REF3325AIDCK?
Yes. The symbol is EasyEDA_Cloud:GM7200AUJZ-2.5-R7 and the footprint Package_TO_SOT_SMD:SOT-323_SC-70, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the REF3325AIDCK?
SC-70-3, with 3 pins. Its footprint is drawn on this page.
Where is the REF3325AIDCK datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the REF3325AIDCK?
JLCPCB lists it as part C139629, with 3,005 in stock; the sellers' links on this page open their listings.
What can replace the REF3325AIDCK?
Parts like it in the library: the ADR5041BKSZ-REEL7 by Analog Devices, the MAX6138AEXR25+T by Maxim Integrated (Analog Devices), the LM4040AEX3-2.5 by Maxim Integrated (Analog Devices) and the LM4040AEX3-2.5+ by Maxim Integrated (Analog Devices). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the REF3325AIDCK?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
