The CXEP3474 is a linear regulator designed to meet the JEDEC SSTL (Series Stub Termination Logic) specifications in DDRI/II/III/IIIL/IV –SDRAM systems. It provides accurate and fast response with up to 1.8A source/sink ability in load transient to track reference voltage. The terminated voltage can be generated by two external resistors or programmed by forcing VREF pin at a desired voltage. Also the CXEP3474 operate in low power consumption as low as 0.7mA and it has a shutdown function by setting VREF lower than 0.15V then the VTT is turned off and discharged via an internal MOSFET. This function obtains low quiescent current as 50μA for STR mode.
