10.1 Power Supply Sequencing
There are no power supply sequencing requirements for all the 1-V and 1.8-V power supplies. For the -1.8 V
VEE18 rail, it is recommended that this supply is the last to be enabled. Enabling VEE18 (while other supply
voltages are disabled) can cause a small negative voltage to be present at the other rails (that is, VDDA1 and
VDDDIG1). This small negative voltage can interfere with the startup of some DC-DC converters or LDO's
connected to the 1 V and 1.8 V input power rails.
