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.

Support DDR I (1.25 VTT), DDR II (0.9 VTT), DDR III (0.75 VTT), DDR IIIL (0.675VTT) and DDR IV (0.6 VTT) Requirements.
VCNTL Supply Voltage: 3V to 5.5V.
Termination Supply Voltage : 1.2V to 3.6V.
Stable with Output Ceramic Capacitor.
Over Current Protection.
Thermal Shutdown Protection.
Shutdown Function for STR (S3) Mode.
Adjustable Output Voltage with Resistors.
Built-In Soft-Start.
Power MOS integrated.
