I have a customer that is trying to combine the 1.3V ADRV9002 rail with DDR3L to limit number of regulators on the board.
In trying to meet the min/max of the ADRV9002 and the DDR3L (taking into consideration the tolerance of the Vref and FB resistors), they are seeing that to set the voltage to a point that satisfies both the rail may be as high as 1.3325V and for margin they want to consider 1.35V.
Datasheet shows 1.33V for operation and 1.5V for max. In reality the 1.3325V is a worse case across temperature and tolerance so for most cases the voltage should be less than 1.33V. But what is the performance or issue that may arise if it does go above 1.33V?
Can you advise?
