Shutdown output duration is automatic when using the EN pin. To get this delay when using I
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.
The quiescent current is calculated as though all regulators are powered up.
