The CXLD64156 linear regulator is designed to provide a regulated voltage with bi-directional output current for DDR-SDRAM termination. The CXLD64156 integrates two power transistors to source or sink current up to 3A. It also incorporate current-limit, thermal shutdown into a single chip. The output voltage of CXLD64156 tracks the voltage at VREF pin. An internal resistor divider is used to provide a half voltage of VREF for VTTREF and VTT Voltage. The VTT output voltage is only requiring 20mF of ceramic output capacitance for stability and fast transient response. The S3 and S5 pins provide the sleep state for VTT (S3 state) and suspend state (S4/S5 state) for device, when S5 and S3 are both pulled low the device provides the soft-off for VTT and VTTREF. The MSOP-10P package with a copper pad is available which provides excellent thermal impedance.
