In my application, previously i have a TPS7A5x LDO to converter 3.3V to 2.5V. But recently, because the power requirement for the loaded device is change to 1.8V. Thus, i want to cascade an another TPS7A52 with previous one. I wonder if in this case, what should pay attention to for this case? Thanks.
3.3V->LDO1->2.5V->LDO1 output Cap->LDO2 input cap->LDO2->1.8V-> LDO2 output cap.
