DDR Termination
Regulator
Features
General Description
The G2995 is a linear
regulator designed to meet the JEDEC SSTL-2 and SSTL-3 (Series Stub Termination Logic) specifications for termination of DDR-SDRAM. It contains a high-speed operational amplifier that provides excellent response to the load transients. This device can deliver 1.5A continuous current and transient peaks up to 3A in the application as required for DDR-SDRAM termination. With an independent VSENSE pin, the G2995 can provide superior load regulation. The G2995 provides a VREF output as the reference for the applications of the chipset and DIMMs. The G2995 can easily provide the accurate VTT and VREF voltages without external resistors that PCB areas can be reduced. The quiescent current is as low as 280µA @ 2.5V. So the power consumption can meet the low power consumption applications.
Operation Supply Voltage: 1.6V to 5.5V Low Supply Current: 280µA @ 2.5V Low Output Offset Source and Sink Current Low External Component Count No Inductor Required No external Resistors Required Thermal Shutdown Protection SOP-8L with Power-Pad package
Applications
