Abstract
Voltage regulators and related methods are described. The voltage regulators described in the application may include an operational amplifier, an output transistor, and a signal buffer connected between the operational amplifier and the output transistor. In some embodiments, these voltage regulators are used in connection with memory units. A voltage regulator may be arranged such that the signal amplifier clamps the voltage at the gate of the output transistor to the output voltage when the memory unit is in an idle mode. In this way, when the memory is accessed, the amplitude and duration of output voltage overshoots can be limited, relative to some voltage regulators.
