This paper presents an output impedance-based approach for designing the voltage regulator (VR) output capacitors at high-slew-rate load current transient. Different types of capacitors are analyzed. Various options for VR output capacitors are discussed and compared. The technology and market trend indicates that the all-ceramic solution is likely to be the most cost-effective approach.
