Summary:An electronic device comprising a first supply voltage domain, a second supply voltage domain and a low drop output voltage regulator (LDO) coupled to receive a supply voltage of the first supply voltage domain and to provide a supply voltage of the second supply voltage domain and the LDO being configured to be switched into a first state for providing and maintaining the supply voltage of the second supply voltage domain and into a second state for providing a high impedance output to the second supply voltage domain. The electronic device includes a comparator coupled to monitor the first supply voltage level at a first supply voltage node and to switch the LDO from the first state to the second state.
