Abstract: A nonwoven fabric for use as packaging in an oral pouched product, where the nonwoven fabric comprises a web of chemically bonded staple fibres in which a relative proportion of staple fibres and a binder is selected in conjunction with a density of the fabric to strike an optimal balance in achieving a fabric that provides a soft (e.g. low friction) mouthfeel, a wet strength capable of withstanding manipulation in a user's mouth (e.g. chewing, sucking or the like), and a resistance to unwanted leaching or leaking of flavouring or other fine particle substances used in modern oral products.

Abstract: A circuit comprising a series voltage regulator comprising a first semiconductor device coupled in series between a supply voltage and a voltage output, the series regulator operable to receive a voltage level from the supply voltage and to provide a regulated voltage level at the voltage output; and a parallel voltage regulator comprising a second semiconductor device coupled to the voltage output, the parallel voltage regulator operable to detect a variation in a voltage level provided at the voltage output, and to sink and/or source a current from/to the voltage output through the semiconductor device, an amount of current sunk and/or sourced adequate to offset the change in the voltage level at the voltage output.

Abstract: A low-dropout voltage regulator includes a power transistor configured to receive an input voltage and to provide a regulated output voltage at an output voltage node. The power transistor includes a control electrode configured to receive a driver signal. A reference circuit is configured to generate a reference voltage. A feedback network is coupled to the power transistor and is configured to provide a first feedback signal and a second feedback signal. The first feedback signal represents the output voltage and the second feedback signal represents an output voltage gradient. An error amplifier is configured to receive the reference voltage and the first feedback signal representing the output voltage. The error amplifier is configured to generate the driver signal dependent on the reference voltage and the first feedback signal. The error amplifier includes an output stage that is biased with a bias current responsive to the second feedback signal.
