Voltage spike when using LM1117

Voltage spike when using LM1117

‎03-13-2019 04:09 AM

Hi,

 

I am trying to make a DC/DC converter with a LM1117 which convert 11V to 9V. I am using a system example from the datasheet. 

So my question is. What causing the voltage spike when switching from "ON" to "OFF" at the switch "S1"

Hello Kasper,

Would you please be so kind to attach your actual MultiSim file? This lowers the threshold to play around with our issue by far, as re-creating the schematics from the screenshot it work...
