Abstract
A hybrid low drop-out (LDO) regulator is provided. The hybrid LDO regulator provides current to a load block, and includes: an analog LDO regulator configured to provide a first current corresponding to an average current consumed by the load block; and a digital LDO regulator configured to provide a second current corresponding to a peak current consumed by the load block based on information indicating the peak current is consumed.
Claims20
A hybrid low drop-out (LDO) regulator which provides current to a load block, comprising:
- an analog LDO regulator configured to provide a first current corresponding to an average current consumed by the load block;
- and
- a digital LDO regulator configured to provide a second current corresponding to a peak current consumed by the load block based on information received from the load block indicating the peak current is consumed.
A hybrid low drop-out (LDO) regulator comprising:
- an analog LDO regulator configured to provide a first current corresponding to an average current consumed in a plurality of load blocks;
- and
- a digital LDO regulator configured to provide a second current corresponding to a peak current consumed by a load block, from among the plurality of load blocks, consuming the peak current based on information received from the load block indicating the peak current is consumed.
A user device comprising:
- an application processor comprising at least one hybrid low drop-out (LDO) regulator;
- and
- a power management integrated circuit configured to provide power to the application processor,
- wherein the at least one hybrid LDO regulator comprises:
- an analog LDO regulator configured to provide a first current corresponding to an average current consumed in a load block;
- and
- a digital LDO regulator configured to provide a second current corresponding to a peak current consumed by the load block based on information received from the load block indicating the peak current is consumed.
