22 / 28 page  ADP5020 Rev. 0 | Page 22 of 2 8 LDO INPUT FILTER To improve the LDO input-to-output ripple suppression in the critical switching frequency range of the buck converters, it may be necessary to add an LC filter tuned to 1 MHz, as shown in Figure 28. Additional tests and simulation must be performed to assess if this filter is necessary. The filter resonance frequency is determined by the following equation: C8 L3 f LC × × π × = 2 1 (3) where L3 = 250 nH, assuming that fLC = 1 MHz and C8 = 100 nF. The inductor must be able to withstand the LDO load current, including the overload condition, which is limited to 400 mA.
