Voltage Regulators - Linear + Switching

Products in this family are used for constructing circuits that perform a DC-DC conversion or voltage regulation function, using a combination of switch-mode and linear regulator functions. While exact topologies vary, the underlying goal of such products is to obtain a combination of the efficiency advantages of switch-mode techniques with the low-noise qualities of linear regulation.
