... Figure 1. Capacitor Requirements Output Capacitor The MIC3975 requires an output capacitor for stable opera- tion µCap LDO, the MIC3975 can operate with ceramic output capacitors as long as the amount of capacitance is 10µF or greater. For values of output capacitance lower than 10µF, the recommended ESR range is 200mΩ to 2Ω. The minimum value of output capacitance recommended for the MIC3975 is 4.7µ ...
