TPS70618DRVR is powered by 3.3V regulator(LDO) and the output is connected to VOC(volatile organic compounds) sensor IC which works on the minimum voltage of 1.68V and nominal voltage of 1.8V. the enable pin of the TPS70618DRVR is connected to output pin of the microcontroller(powered by 3.3V). but if we observe the voltage of the output of LDO and the Enable pin we found that there is a some glitch in the enable signal and the output of 1.8V (refer the below picture). the Problem we are facing is we are not able to read the VOC data which is powered by this 1.8V. This issue we are facing with the TPS70618DRVR part but with the TPS78218DRVT it works fine.
