Hi,
I am new to the forum. I am working on a project that involves a 6volt (4 AA) battery supply and the main ICs are running on 3.3v. I have tried LD1117S33 with Caps filter as it recommended in the APP but I am getting a spike max 4v when I unhook and re-hook the battery (4 AA) at power up. Is MIC5205-3.3 LDO more stable then the LD1117S33? I am trying to get rid of the voltage spike and stay away from ferrite beads if possible. I have attached my power up circuit below.
Thanks,
Sheng
