(Newbie) Footprint question

I have completed my schematic drawings and struggling to find right foot prints for the regular chips: LM1117 and LM7805. Furthermore, I read on some other thread that the pin headers are called connectors.But which ones have the same footprint as these female header pins: https://www.sparkfun.com/products/115

I don’t want to use the solder mount ones . Too tiny and will likely mess it up. I would prefer to use the through the holes components .So can I some help in identifying the foot prints, or just point me to the correct directions.

Also, is there a guide/tutorial on how to use the footprint library properly or in a better way. Currently when I am using it, it shows the whole library and I have to keep scrolling through the list.


Starting with the easy one, for typical 0.1 connectors look in Pin_Headers, e.g. Pin_Header_Straight_1x03_Pitch2.54mm

7805 from the official regul.lib is an oddity, there is no official footprint for it I can find (unless added recently). I have my own versions for that symbol, using TO_SOT_Packages_THT:TO-220_Neutral123_Vertical.

LM1117 has several possible footprints, need to be more specific.

Look in the Pin_Headers or Socket_Strip library.
If you don’t have them:
open pcb_new
go to preferences->footprint library wizard
Select github repository with https://github.com/KiCad in the input field
(only select save local copy if you don’t want kicad to download the libs everytime they are needed.)
Press next.
In the next window press select all.
Finish the wizard. (follow the instructions you get there.)

I looked at the datasheet for LM1117 by ti. http://www.ti.com/lit/ds/symlink/lm1117.pdf
Ti produces this chip in 4 different packages:

  • SOT-223
  • TO-220
  • TO-252
  • TO-263

We do not know which one you want (or which one is available to you. All of them are somewhere in the library (TO_SOT_Packages_SMD and TO_SOT_Packages_THT)

Okay, thank you and if I don’t have them. I will follow your instructions.
