The SC488 is a combination switching regulator and linear source/sink regulator intended for DDR1/2 memory systems.

include cycle-by-cycle current limiting, digital soft-start, over-voltage and under-voltage protection and a power good ﬂag. For the VTT regulator, the output voltage tracks REF, which is ½ VDDQ to provide an accurate termination voltage. The VTT output is generated from a 1.2V to VDDQ input by a linear source/sink regulator which is designed for high DC accuracy, fast transient response, and low external component count. All three outputs (VDDQ, VTT and REF) are actively discharged when VDDQ is.
