Abstract
A method and system are provided for supplying power with an LDO linear voltage regulator () having an LDO power supply () and a load switch () by connecting a power supply voltage () to a main core () and a standby core () in a multi-core low power microcontroller () during an active mode so that the standby core receives a first supply voltage that tracks the power supply voltage during the active mode, and upon detecting a standby mode for the multi-core low power microcontroller, disconnecting the power supply voltage from the standby core and connecting a low dropout (LDO) linear power supply voltage to the standby core during the standby mode so that the standby core receives the LDO linear power supply voltage as a second supply voltage during the standby mode.
