Product Folder Sample & Buy Support & Community Tools & Software Technical Documents TPS51206 SLUSAH1B – MAY 2011 – REVISED DECEMBER 2014 TPS51206 2-A Peak Sink / Source DDR Termination Regulator With VTTREF Buffered Reference for DDR2, DDR3 and DDR3L 1 Features 3 Description • The TPS51206 is a sink / source double date rate (DDR) termination regulator with VTTREF buffered reference output. It is specifically designed for lowinput voltage, low-cost, low-external component count systems where space is a key consideration. The TPS51206 maintains fast transient response and only requires 1 × 10-µF of ceramic output capacitance. The TPS51206 supports a remote sensing function and all power requirements for DDR2, DDR3 and Low-Power DDR3 (DDR3L) VTT bus. The VTT current capability is ±2-A peak. The TPS51206 supports all of the DDR power states, putting VTT to High-Z in S3 state (suspend to RAM) and discharging VTT and VTTREF in S4/S5 state (suspend to disk). 1 • • • • • • Supply Input Voltage: Supports 3.3-V Rail and 5-V Rail VLDOIN Input Voltage Range: VTT+0.4 V to 3.5 V VTT Termination Regulator – Output Voltage Range: 0.5 V to 0.9 V – 2-A Peak Sink and Source Current – Requires Only 10-μF MLCC Output Capacitor – ±20 mV Accuracy VTTREF Buffered Reference – VDDQ/2 ± 1% Accuracy – 10-mA Sink / Source Current Supports High-Z in S3 and Soft-Stop in S4/S5 with S3/S5 Inputs Overtemperature Protection 10-Pin 2-mm × 2-mm SON (DSQ) Package The TPS51206 is available in 10-pin, 2 × 2, SON (DSQ) PowerPAD™ package and specified from –40°C to 85°C.
