I would not recommend attempting to build one of these boards unless you have and know how to use the following equiment:

Texas Instruments
-40℃~+125℃@(Tj) 1 1A 200uV 26V 3V~24V 600mV@(1A) 60dB 700uA Adjustable Negative Over Current Protection、Over Temperature Protection、Short Circuit Protection TO-220-5 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS
The LM2991T is a voltage Regulators Linear, Low Drop Out (LDO) Regulator made by Texas Instruments in a TO-220-5 package with 5 pins. -40℃~+125℃@(Tj) 1 1A 200uV 26V 3V~24V 600mV@(1A) 60dB 700uA Adjustable Negative Over Current Protection、Over Temperature Protection、Short Circuit Protection TO-220-5 Voltage Regulators - Linear, Low Drop Out (LDO) Regulators ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:LM2991T_NOPB, from EasyEDA) and its footprint (Package_TO_SOT_THT:TO-220-5_Vertical, from KiCad's library), ready for a KiCad board. 386 are in stock at JLCPCB (part C2860450). 3 open-source boards in 2 repositories on GitHub use it.

The symbol is EasyEDA_Cloud:LM2991T_NOPB and the footprint Package_TO_SOT_THT:TO-220-5_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
TO-220-5, with 5 pins. Its footprint is drawn on this page.
Texas Instruments publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C2860450, with 386 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the LM2941TG by HANSCHIP semiconductor, the LM2941T by HGSEMI, the MIC29151T-5.0 by HGSEMI and the MIC39301T-3.3 by HGSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
3 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
