The SGM2054 device is a sink and source double data rate (DDR) termination regulator. It is specifically designed for low-cost and low-external component count systems.

The SGM2054 provides fast transient response and only requires a minimum 20μF output capacitance. The SGM2054 supports remote sensing functions and all features required to power the DDR2, DDR3, DDR3L, Low-Power DDR3, DDR4 and DDR5 VTT bus termination. In addition, the SGM2054 provides an open-drain PGOOD to monitor the output regulation. EN signal that can be used to discharge VO when EN less than 0.3V.

The SGM2054 is available in a Green TDFN-3×3-10L package. It operates over an operating temperature range of -40℃ to +125℃.
