The ON Semiconductor NCP51145MNTAG is a linear regulator specifically designed to provide a regulated VTT termination voltage for DDR-II, DDR-III, LPDDR-III, and DDR-IV memory applications. This device is capable of actively sourcing and sinking peak currents up to ±1.8 A, ensuring stable termination voltage regulation within ±20 mV.
Key electrical features include an input voltage range of 1.0 V to 5.5 V and an output voltage that tracks VDDQ/2. The regulator incorporates a high-speed differential amplifier for ultra-fast response to line and load transients. It also includes integrated power MOSFETs, source/sink current limiting, soft-start functionality, and on-chip thermal shutdown protection.
The NCP51145MNTAG is supplied in an 8-DFN (2x2mm) package, suitable for surface mounting. Its operating temperature range is -40°C to 85°C, making it suitable for a variety of computing and consumer electronics applications.
Typical applications include memory termination voltage for motherboards, notebooks, VGA cards, set-top boxes, and digital TVs. The device supports various DDR standards, including DDR-II, DDR-III, and DDR-IV.
