Product Details

General Description

The RT9045 is a simple, cost-effective and high-speed linear regulator designed to generate termination voltage in Double Data Rate (DDR) memory system to comply with the devices requirements. The regulator is capable of actively sinking or sourcing up to 1.8A while regulating an output voltage to within 20mV. The output termination voltage can be tightly regulated to track VDDQ/ 2 by two external voltage divider resistors or the desired output voltage can be programmed by externally forcing the REFEN pin voltage.

Features

Ideal for DDR VTT Applications
Sink and Source Current :
DDRII 1.8A Sink/Source @ VIN = 1.8V
DDRIII 1.5A Sink/Source @ VIN = 1.5V
LPDDRIII 1.2A Sink/Source @ VIN = 1.35V
`DDRIV 1.2A Sink/Source @ VIN = 1.2V
Integrated Power MOSFETs
Generate Termination Voltage for DDR Memory Interfaces
Stable with Output Ceramic Capacitor
High Accuracy Output Voltage at Full-Load
Output Adjustment by Two External Resistors
Low External Component Count
Shutdown for Suspend to RAM (STR) Functionality with High Impedance Output
Current Limiting Protection
On-Chip Thermal Protection
RoHS Compliant

Applications

Desktop PCs, Notebooks, and Workstations
Graphics Card Memory Termination
Set Top Boxes, Digital TVs, Printers
Embedded Systems
Active Termination Buses
DDR Memory Systems
