8.1.2 Unused Regulators

In case a step-down converter is not used, its input supply voltage pin VINDCDCx still needs to be connected to the VCC rail along with supply input of the other step-down converters. TI recommends closing the control loop such that an inductor and output capacitor is added in the same way as it would be when operated normally. If one of the LDOs is not used, its output capacitor must be added as well. If both LDOs are not used, the input supply pin as well as the output pins of the LDOs (VINLDO, VLDO1, VLDO2) must be tied to GND.
