Hi expert,
Our customer is referring to AM275 EVM. They would like to know why PVIN_LDO3 is using VCC1V8_SYS as input instead of 5V? Is there any special consideration?

Best Regards,

Xingyu Zhu,
Since LDO3 is used for VDDR_CORE (0.85V), a lower input voltage for the LDO results in lower power dissipation.
