Abstract
The present disclosure relates to a device comprising: N low drop-out voltage regulators, N being an integer greater than or equal to 1; a first circuit configured to deliver N set-point voltages to the N regulators which are proportional to the same first current; and a second circuit configured to deliver the first current, wherein the first current is proportional to a reference current modulated based on a sum of the inrush currents of the N regulators.
Claims20
A device, comprising:
- one or more low drop-out voltage regulators;
- a first circuit coupled to the one or more low drop-out voltage regulators, the first circuit configured to deliver N set-point voltages to the one or more low drop-out voltage regulators, wherein N is a quantity of the one or more low drop-out voltage regulators, and wherein each of the N set-point voltages is proportional to a first current;
- and
- a second circuit coupled to the first circuit, the second circuit configured to generate the first current proportional to a reference current modulated based on a sum of in-rush currents received from the one or more low drop-out voltage regulators.
