Abstract
An electronic device including a low dropout regulator having an output coupled to a first conduction terminal of a transistor, with a second conduction terminal of the transistor being coupled to an output node of the electronic device. A method for operating the device to switch into a power on mode includes: turning on the low dropout regulator, removing a DC bias from the second conduction terminal of the transistor, and turning on the transistor. A method for operating the device to switch into a power down mode includes: turning off the transistor, forming the DC bias at the second conduction terminal of the transistor, and turning off the low dropout regulator.
