There is considerable noise (spikes) in measurements of output ripple voltage. Please describe the recommended measurement environment.
- Use a passive probe for measurement of both ends of the output capacitor. At this time, the GND lead of the probe is not used, and grounding should be such that the loop area of the measurement points and GND is made as small as possible. Moreover, a probe must be used with a sufficient frequency band relative to the frequency being measured.
