Questions

Is there a KiCad symbol and footprint for the OB2273AMP?

Yes. The symbol is EasyEDA_Cloud:MX1210R and the footprint Package_TO_SOT_SMD:SOT-23-6, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the OB2273AMP?

SOT-23-6, with 6 pins. Its footprint is drawn on this page.

Where is the OB2273AMP datasheet?

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

Where can I order the OB2273AMP?

JLCPCB lists it as part C78847, with 14,500 in stock; the sellers' links on this page open their listings.

What can replace the OB2273AMP?

Parts like it in the library: the OB2263MP by OB, the OB2362AMP by OB, the LP3320B6F by LOWPOWER and the SIP32509DT by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
