I am trying to use a 555 timer in my circuit to produce a signal (rather generally) above 100kHz. I have been successful with this goal, but have had an issue where the voltage measured on my positive and GND rails drops significantly whenever there is a change.
I am using a bench supply that is set to supply 9v at a maximum of 80mA, but the whole circuit only draws 19mA when operational.
This voltage drop is causing the other ICs in my circuit to not work properly.
My guesses is that there is a capacitor somewhere that is too large or small, that this is a property of the power supply or 555 timer, or that the sudden change of voltage requires a lot of current to drive that I somehow cannot detect with my power supply.
Is there any way that I can minimize the voltage drop of my source?
