LP2996MR/NOPB General Description

The LP2996-N and LP2996A linear regulators are designed to meet the JEDEC SSTL-2 specifications for termination of DDR-SDRAM. The device also supports DDR2, while LP2996A supports DDR3 and DDR3L VTT bus termination with V_DDQ minimum of 1.35 V. The device contains a high-speed operational amplifier to provide excellent response to load transients. The output stage prevents shoot through while delivering 1.5-A continuous current and transient peaks up to 3 A in the application as required for DDR-SDRAM termination. The LP2996-N and LP2996A also incorporate a VSENSE pin to provide superior load regulation and a VREF output as a reference for the chipset and DIMMs.

An additional feature found on the LP2996-N and LP2996A is an active-low shutdown (SD) pin that provides Suspend To RAM (STR) functionality. When SD is pulled low the VTT output will tri-state providing a high impedance output, but VREF remains active. A power savings advantage can be obtained in this mode through lower quiescent current.

TI recommends the LP2998 and LP2998-Q1 devices for automotive applications and DDR applications that require operating at temperatures below zero.

WEBENCH^® design tools can be used by application designers to generate, optimize, and simlulate applications using the LP2998 and LP2998-Q1.

Corresponds to the description. Delivery fast 5 days

L**n 07/05/2022

Great cost, recommend.Arrived super fast

S**a 06/03/2021

Items received and all tested ok.However, all 70 DIP chips were thrown into a plastic bag and shipped.Thus some leads were bent and had to be straightened.This is very poor practice.
