Hi,
I use different buck-boost and boost voltage regulators to generate typically 3.3V and 5V from a 3.7V Li-Ion battery in my designs. I notice that the ripple is a bit high; typically 40-65mV. I have added 2-3 22uF ceramic capacitors and a 100nF capacitor on the input and output of the regulators, but I still have the high voltage ripple.
How can I get rid of/minimize the voltage ripple?
