Hi team
Customer encounter an issue when using TPS659037 in their system.
They found LDO1 output/ RESET_OUT will stay in a "voltage platform" for a while before ramp up to target output voltage.
Customer want to know is it normal? Why TPS659037 will have such behaviours?
Below waveform is captured without any I2C configuration.
The first waveform is LDO1(BLUE) and LDO2(YELLOW) output。 LDO1 will stay at 1V for a while during ramp up.
The second waveform is LDO2(YELLOW) and RESET_OUT(BLUE)
