The Texas Instruments LP2998MRX/NOPB is a linear regulator specifically designed for DDR-SDRAM and DDR2 memory termination, also supporting DDR3 and DDR3L VTT bus termination. It meets JEDEC SSTL-2 and JEDEC SSTL-18 specifications.
This regulator features a wide input voltage range from 1.35V to 5.5V and a tightly controlled output voltage range of 0.656V to 0.698V. It can deliver 1.5A of continuous current and transient peaks up to 3A, essential for DDR-SDRAM termination requirements. The device includes a shutdown pin for Suspend To RAM (STR) functionality, allowing the VTT output to tri-state.
With a low quiescent current of 0.32mA typical, the LP2998MRX/NOPB is suitable for power-sensitive applications. It is available in an 8-SO PowerPad package, designed for surface mounting. The operating temperature range is -40°C to 125°C (TJ), ensuring reliable performance in various environments.
Key features include a high-speed operational amplifier for excellent transient response, a VSENSE pin for superior load regulation, and a VREF output for chipset and DIMM reference. The AEC-Q100 qualified device exhibits an HBM ESD Classification Level of H1C.
