  • Regulating apparatus with soft-start and fast-shutdown function
    Patent number: 8670251
    Abstract: A regulating apparatus with soft-start and fast-shutdown function is applied to a voltage-supplying apparatus. The regulating apparatus includes a soft-start and fast-shutdown circuit, a regulating circuit, and a ground circuit. When voltages are supplied from the voltage-supplying apparatus to the soft-start and fast-shutdown circuit, the regulating circuit, and the ground circuit, the ground circuit is connected to ground, so that the starting time of the regulating circuit is delayed by the soft-start and fast-shutdown circuit. When voltages are not supplied from the voltage-supplying apparatus to the soft-start and fast-shutdown circuit, the regulating circuit, and the ground circuit, the ground circuit is not connected to ground, so that the regulating circuit is shut down fast by the soft-start and fast-shutdown circuit.
