1. An apparatus, comprising:
a substrate;
a first die positioned above the substrate in a first direction, the first die comprising a component configured to generate a voltage for use by the first die, the component comprising a first output terminal coupled with operating circuitry of the first die, the first output terminal configured to transfer the voltage to the operating circuitry;
a second die positioned above the substrate in the first direction, the second die comprising a capacitor configured to regulate the voltage generated by the first die;
a first conductive line that is configured to couple a first terminal of the capacitor of the second die with a second output terminal of the component on the first die that is configured to generate the voltage, wherein a first portion of the first conductive line extends in a second direction within the substrate, the second direction different from the first direction; and
a second conductive line that is configured to couple a second terminal of the capacitor of the second die with a third output terminal of the component on the first die.
