A voltage regulator includes a regulator input connected to a reference voltage; a regulator output that outputs a regulated voltage to an electrical load; a first loop, the first loop configured to receive the reference voltage, the first loop outputting a bias voltage; a second loop, the second loop configured to receive the bias voltage as an input; and a bias voltage capacitor connected to a node between the first loop and the second loop.

A memory device includes memory cells, each of the memory cells having corresponding bit and word lines connected thereto for accessing the memory cells, a word line circuit coupled with at least one word line, and a bit line circuit coupled with at least one bit line. The memory device further includes at least one control circuit coupled with the bit and word line circuits. The control circuit is operative to cause state information to be stored in the memory cells. At least one switching element selectively connects the memory cells, the bit and word line circuits, and the control circuit to at least one power supply as a function of at least one control signal. The control circuit generates the control signal for disconnecting at least portions of the word line and bit line circuits from the power supply while state information is retained in the memory cells.

A flashlight having a self-extingushing feature that prevents unintentional run-down of its batteries, particularly when used by children, which is achieved by means of a circuit breaking device controlled by a timer, and further having a bypass switch, preferably of a child-proof nature, to override the self-extinguishing feature and thereby improve the utility of such flashlight as an ordinary household flashlight. Optionally, the flalshlight may also have additional "child-proofing" mechanisms such as an interlock to prevent unintended activation of the bypass switch.

An apparatus for providing a local reference voltage for a voltage regulator includes a reference capacitor configured to provide the local reference voltage, a charge pump configured to push current to, or pull current from, the reference capacitor according to one or more control inputs received by the charge pump, and a boosting circuit configured to add or subtract a discrete quantity of charge to the reference capacitor according to one or more boosting control signals. A boosting control circuit may be configured to disconnect a boosting capacitor from the reference capacitor during a first phase of a control cycle and connect the boosting capacitor to the reference capacitor during a second phase of the control cycle. The boosting capacitor may be pre-charged (to add charge) or discharged (to subtract charge) during the first phase of the control cycle. A corresponding method is also disclosed herein.
