PRODUCTION DATA
The VTT LDO must handle the fast load transients from the DDR memory for termination. Therefore, it is recommended to use ceramic capacitors to maintain a high amount of capacitance with low ESR on the VTT LDO outputs and inputs. The preferred output capacitors for the VTT LDO are the GRM188R60J226MEA0 from Murata (22 µF, 0603, 6.3 V, ±20%, or similar capacitors). The preferred input capacitor for the VTT LDO is the CL05A106MP5NUNC from Samsung (10-µF, 0402, 10-V, ±20%, or similar capacitor).
The remaining LDOs must have input and output capacitors chosen based on the values in Section 6.9.
