>Voltage regulators are designed to maintain a stable output voltage, but they generally do not block current transients. Instead, they aim to respond to changes in load current or input voltage by adjusting their internal circuitry to maintain the desired output voltage. They often include current limiting features to protect against overcurrent conditions, but they do not typically filter or suppress current spikes.
so the 47uF should be low leakage current

what about the 100nF, i haven't read the article below yet, is it best to leave them alone in the existing design or mod them
