Quoting Philipp Zabel: "Since this regulator is used as the TVDAC analog power supply, this range should at least be limited to the analog power supply range of the TVDAC, listed in Table 74-9. of the i.MX53 reference manual (2.5-2.75V). But since the nominal voltage is 2.75V, which was used to determine the analog gain that is supposed to result in the necessary 0.7V peak-to-peak amplitude on the VGA output, I'd say we should just fix the voltage to 2750000 here." , so limit the TVDAC analog power supply as suggested.
