I did insert in schematic the LD1117 V3.3, from Sparkun library. I need to convert 5V to 3v3.

Device selected is V_REG_LD1117VXX, package 78XXL.

I want use it for LM1117v33 (or LD1117V33). This is the datasheet:


When I did switch to board, seems to me that PINOUT is inverted (from Left to Right I red IN/GND , GND/3.3V and OUT/5V) and also the names on it are wrong.

I attach an imagine (small and larger). Where am I wrong? Thank you very much.

    \$\begingroup\$ I just looked up the datasheet for AMS1117 and it has no PTH version. Please provide a datasheet for the device you are referring to. (also, 78XXL is not a package name, its a family of another ubiquitous regulator. So if the library has mixed names for devices, its likely that the actual package is not for the AMS1117) \$\endgroup\$ – Wesley Lee Oct 16 '17 at 19:49
  • \$\begingroup\$ Always verify third party libraries, SparkFun makes a lot of parts that are never device-proven. It isn't unrealistic to find a part that is incorrectly made. Luckily it looks like a standard package, it would be very easy to make your own part. \$\endgroup\$ – Ron Beyer Oct 16 '17 at 20:19
  • \$\begingroup\$ @WesleyLee You are right. I did wrong the name of selected components. Edited question. Thank you \$\endgroup\$ – sineverba Oct 16 '17 at 20:22
  • \$\begingroup\$ I looked into the datasheet, seems that the connections are different than the package. The order in the package is the same as in the 78XX family, so I think this is a different device that happens to be in the wrong "place". \$\endgroup\$ – Wesley Lee Oct 16 '17 at 20:29
  • \$\begingroup\$ Old library, wrong connections? I tried V_REG_LD1117VXX from 'SparkFun-IC-Power.lbr' on github and pinout was correct, but package is slightly different to yours - which suggests your library is an old or modified version. Note that text 'I - O' on the package does not match the actual pin functions. \$\endgroup\$ – Bruce Abbott Oct 17 '17 at 1:43
