Application Notes
- AN-1254 DDR-SDRAM Termination Simplified Using a Linear Regulator (Rev. A)PDF, 66 Kb, Revision: A, File published: May 6, 2013
This applications report describes the use and benefits of the LP2995 for DDR-DRAM Termination. - Limiting DDR Termination Regulators’ Inrush CurrentPDF, 772 Kb, File published: Aug 23, 2016
The output voltage of DDR termination regulators tends to rise quickly after their VDDQ line is enabled. Most DDR terminators are specifically designed for fast start-up. They also require bulky output capacitors for a stable output voltage. This often results in a significant inrush current from DDR terminator voltage supply to charge the output capacitors and to provide curre
