LM34927: LM34927 output voltage is too high

Part Number: LM34927

Hi sir
I use _LM34927 to output 12V voltage, calculate the feedback resistor and Vref error, the worst case VOUT is 12.54V,but the actual test, some boards VOUT exceeds 12.6V,when I remove the capacitor C179, VOUT becomes 12.2V, the ripple of VFB has also become larger, and I want to ask what is the specific calculation formula of C179 affecting VOUT value.thanks ,the inserted file is test data and schematic.LM34927 12V_AUX test data and Schematic.xlsx
