The AXP209 LDO3 regulator supports voltage rate control, or can set a slew rate.
This allows for the power to gradually rise up to the desired voltage, instead of spiking up as fast as possible. Reason to have this can be to reduce the inrush currents for example.
There are 3 slopes to choose from, the default, 'none' is a voltage rise of 0.0167 V/uS, a 1.6 mV/uS and a 0.8 mV/uS voltage rise.
In ideal world (where vendors follow the recommended design guidelines) this setting should not be enabled by default. Unless of course AXP209 crashes instead of reporting overcurrent condition as it normally should do in this case.
