Abstract
An integrated circuit (IC) with voltage regulation includes high power and low power domains, low and high voltage regulators and a low power regulator. The low voltage regulator powers the high and low power domains when the IC is in a HIGH power mode. The low power regulator receives a voltage from a high voltage regulator and powers the low power domain when the IC is in a LOW power mode. The IC includes a switching module that disconnects the low voltage regulator from the low power domain when the output voltage of the high voltage regulator is lower than a threshold voltage during power-up and connects the low voltage regulator to the low power domain when the voltage regulated by the high voltage regulator exceeds the threshold voltage.
