NCP51401MNTXG

The NCP51401MNTXG from On Semiconductor is a specialized DDR termination regulator designed for applications requiring low input voltage and minimal noise. This device supports DDR1, DDR2, DDR3, LPDDR3, and DDR4 memory termination, making it versatile for various computing and networking platforms.

Key electrical specifications include input voltage rails supporting 2.5V, 3.3V, and 5V, with a PVCC voltage range from 1.1V to 3.5V. The output voltage can be adjusted from 0.5V to 1.8V. It features integrated power MOSFETs, droop compensation, and a fast load-transient response, requiring a minimum output capacitance of 20 µF.

The NCP51401MNTXG operates within a temperature range of -40°C to 125°C. It is housed in a compact, thermally-efficient 10-DFN (3x3) exposed pad package, suitable for space-constrained designs. The regulator includes features like PGOOD for monitoring VTT regulation, EN for shutdown mode, and VRI for flexible input tracking. It also supports remote sensing (VTTS) for accurate feedback.

This device is rated as Pb-free and RoHS compliant, making it suitable for environmentally conscious designs. Applications include DDR memory termination in desktop PCs, notebooks, workstations, servers, networking equipment, and graphics processor core supplies.
