A low power low dropout linear voltage regulator

摘要

Embodiments of a linear voltage regulator are described. In one embodiment, the linear voltage regulator includes a PMOS low drop-out (LDO) regulator configured to convert an input voltage to a regulated voltage, a charge pump connected to the PMOS LDO regulator and configured to amplify the regulated voltage into an amplified voltage, and an NMOS LDO regulator connected to the charge pump and configured to convert the amplified voltage into an output voltage. Other embodiments are also described.
