1 The VDD_IO voltage must be less than or equal to the level on the VDDx supply lines.
2 Shutdown output duration is automatic when using the EN pin. To get this delay when using I2C, FORCE_XS must be set to 1.
3 Activation delays apply only when the device is activated through the EN pin or the EN_ALL bit (Address 0x03[4]); the sequencer controls the turning on of the
regulators.
4 The quiescent current is calculated as though all regulators are powered up.
