TPS51200MDRCTEP

Special Purpose Regulators Overview

The TPS51200MDRCTEP is a sink/source DDR termination regulator from Texas Instruments, designed for low-input-voltage, space-constrained systems. It supports DDR, DDR2, DDR3, DDR3L, and DDR4 VTT bus termination with a 3 A output current capability. The device operates within an input voltage range of 1.1 V to 3.5 V and provides an adjustable output voltage up to 1.25 V. It features remote sensing for precise regulation and requires a minimum output capacitance of 20 μF. The component is housed in a 10-pin VSON package with a thermal pad, rated for operation between -40°C and +85°C.

Special Purpose Regulators Feature Summary

• Sink and source DDR termination regulator with dropout compensation
• Remote sensing (VOSNS) for accurate memory terminal voltage monitoring
• Buffered reference output (REFOUT) for VTTREF generation
• Integrated protection including soft-start, UVLO, overcurrent limit, and thermal shutdown

Special Purpose Regulators Applications

• Memory termination regulators for DDR, DDR2, DDR3, DDR3L, and DDR4
• Notebooks, desktops, and servers
• Telecommunications and data communications equipment
• Base stations, LCD/Plasma TVs, copiers, printers, and set-top boxes

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'MDRCTEP' against the official Texas Instruments datasheet to confirm it denotes the tape-and-reel packaging variant of the TPS51200 series. Ensure that the environmental or reliability specifications match the standard commercial grade requirements for your application, as suffixes may indicate specific handling or packaging configurations rather than functional changes.

Special Purpose Regulators Selection Notes

Select this component when designing systems requiring fast transient response for DDR memory buses with minimal output capacitance constraints. It is suitable for applications needing integrated PGOOD signaling and EN control for power sequencing. Consider the 10-pin VSON package for space-limited layouts and ensure the input voltage rail falls within the 1.1 V to 3.5 V operational window.

Special Purpose Regulators Part Context

The TPS51200 series consists of sink/source DDR termination regulators optimized for low-noise, low-cost environments. The TPS51200MDRCTEP belongs to this family, providing dedicated VTT power management. It complements other TI PMICs by handling the specific dynamic load requirements of modern memory standards while maintaining high efficiency and compact footprint through its advanced VSON packaging technology.

Special Purpose Regulators Replacement Considerations

The TPS51200DRCTG4 is a verified equivalent part number within the same product family, offering identical electrical characteristics and functionality. Other variants such as TPS51200DRCR or TPS51200AQDRCTQ1 may serve as alternatives depending on automotive qualification or specific packaging needs.
