Abstract: An output circuit including an output transistor configured to provide an output signal; and a gate switch configured to decouple a gate of the output transistor from other components of the output circuit when there is a decrease in a supply voltage of the output circuit, wherein when the gate of the output transistor is decoupled, a charge at the gate is maintained in a capacitor inherent within the gate of the output transistor.
