My question is that, are these short pulses of 4.6 v is tolerable ? And can anyone specify what are ways this ripples can be reduced?
thank you.
You could use an LDO or TVS diode to reduce the spikes. But better to look first at your 3.3v regulator, why is it passing such spikes through. Is the feedback loop node receiving noise? Is the output capacitance too low? Need to see schematic and pcb.And can anyone specify what are ways this ripples can be reduced?
