built-in current limiting. For a given capacitor, a larger applied voltage within the voltage rating of the capacitor, will give a larger leakage current. Measuring a larger current with the same intrinsic noise floor produces a greater signal-to-noise ratio, and a more accurate reading. For capacitors with high voltage ratings, a 1000V source ...

Otherwise, the capacitor loses much of its capacitance due to dc bias or temperature. The value can be increased if the input voltage is noisy. 7 Output Capacitor Selection The best practice is to use low-ESR capacitors to minimize the ripple on the output voltage. Ceramic capacitors are a good choice if the dielectric material is X5R or better.
