NCV51510MWTAG

The NCV51510MWTAG from On Semiconductor is a specialized voltage regulator designed for DDR memory termination. It functions as both a source and sink regulator, supporting DDR, DDR-2, DDR-3, and DDR-4 standards. This device is engineered for low input voltage and low-noise applications where space is a critical factor.

Key features include the ability to handle loads up to ±3 A (typical) with over-current protection and integrated MOSFETs with thermal shutdown. It offers a fast transient response and requires a minimum VTT load capacitance of 10 µF for stability. The regulator supports remote sensing via a VTTS input and provides flexible voltage tracking through a VRI input reference. Additional features include a PGOOD output pin for monitoring regulation status and an SS input for suspend shutdown mode.

The NCV51510MWTAG is housed in a compact, low-profile 10-pin, 3x3 mm DFN package with an exposed pad for efficient thermal management. It operates within a temperature range of -40°C to 125°C. The NCV variant is suitable for automotive and other applications requiring unique site and control change requirements, with AEC-Q100 qualification and PPAP capability available for specific part numbers.

This regulator is ideal for applications such as desktop PCs, notebooks, workstations, servers, networking equipment, telecom/datacom systems, and graphics processor core supplies. It can supply power for chipsets and RAM as low as 0.5 V, making it versatile for various low-power designs.
