Hi,
I have a 3.3V linear regulator that I want to use to clamp 24V to via a 100K
resistor and a diode. Im pretty sure this is ok but just wanted to double
check. Does anyone have any feedback?
Depending on the load, it could potentially drag the 3.3v rail upwards.
A more universal solution would be to use an opamp set as a unity-gain buffer, powered from the
supply into the 3v3 reg, with the input from the 3.3v supply.
