The SY20775 is a sink and source double data rate memory (DDR) regulator designed for applications that require very low noise and low input voltage systems.
It supports power requirements for DDR, DDR2, DDR3, DDR3L, and DDR4 VTT BUS termination, and it uses remote sensing for increased output voltage accuracy and a fast transient response. Additionally, it has an enable pin to control VTT discharge during low power modes in DDR applications, and a PGOOD pin to monitor output regulation.
The SY20775 is available in a DFN 3mm×3mm-10pin package with exposed thermal pad and it operates over a temperature range of -40°C to 85°C.
