I built up a design using the ADP5050 LDO to create 3.3V from a 5.0V input. I selected 1% resistors to get 3.3V with the 0.5V internal reference. I built up several PCB but am not getting 3.3V. 1st is 3.8V (feedback is 0.58V), and the second is 3.5V (feedback is 0.535V). Per the datasheet the feedback reference should be 0.50 +/-1%. I am using 56.2K top resistor, and 10K bottom resistor. Any ideas what is going on here?
