G2987 Description
The G2987 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.
