Overview
The LM2991S is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by Texas Instruments in a TO-263-5 package with 6 pins. -40℃~+125℃@(Tj) 1 1A 26V 3V~24V 600mV@(1A) 60dB@(1kHz) 700uA Adjustable Negative Over Current Protection、Over Temperature Protection、Enable TO-263-5 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.
PCBKit's library has its KiCad symbol (Regulators:LM2991S, from CERN's library) and its footprint (Package_TO_SOT_SMD:TO-263-5_TabPin6, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C205474).

Is there a KiCad symbol and footprint for the LM2991S?
Yes. The symbol is Regulators:LM2991S and the footprint Package_TO_SOT_SMD:TO-263-5_TabPin6, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the LM2991S?
TO-263-5, with 6 pins. Its footprint is drawn on this page.
Where is the LM2991S datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the LM2991S?
JLCPCB lists it as part C205474, with 0 in stock; the sellers' links on this page open their listings.
What can replace the LM2991S?
Parts like it in the library: the SPX29302T5-L/TR by MaxLinear, the LM29302AS/TR by HGSEMI, the MIC39302S/TR by HGSEMI and the LM29302R by HTC Korea TAEJIN Tech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
