Thank you for this. Just so you're aware for future questions, the customer believes they found the problem. It appears to be due to the 200mV POR issue. The recommended resistor values for the feedback divider on the TPS7A2601DRVR are too high to quickly bleed the voltage off the bulk capacitance on the rail. They lowered the resistor values so that the feedback divider more aggressively drains the rail when the regulator is disabled.
