Questions

Is there a KiCad symbol and footprint for the REF3030AIDBZR?

Yes. The symbol is Reference_Voltage:REF3030 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the REF3030AIDBZR?

SOT-23, with 3 pins. Its footprint is drawn on this page.

Where is the REF3030AIDBZR datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the REF3030AIDBZR?

JLCPCB lists it as part C38423, with 28,536 in stock; the sellers' links on this page open their listings.

What can replace the REF3030AIDBZR?

Parts like it in the library: the GM7200AUJZ-3.0-R7 by GONGMOSEMI, the GM7210AUJZ-3.0-R7 by GONGMOSEMI, the ADR530BRTZ-REEL7 by Analog Devices and the LT1460HCS3-3#TRMPBF by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
