  • Patent number: 8232677
    Abstract: A multi-supply power supply circuit has a first power supply regulating circuit that produces a first power supply voltage; and a second power supply regulating circuit that receives the first power supply voltage from the first power supply regulating circuit as an enable input signal and is operative to produce a second and different power supply voltage. In one embodiment, the first power supply voltage may reach a steady state condition prior to the second power supply voltage reaching a steady state condition. In one example, the multi-supply power supply circuit includes a plurality of cascaded low drop out power supply regulating circuits.
