Abstract: Provided is voltage regulator circuit including an input node for receiving an input supply voltage, an output node for producing an output regulated voltage, and a switchable pass element arranged between the input and output nodes. A comparator circuit compares the output regulated voltage to a dynamic threshold to produce a control signal to control the switchable pass element. The control signal being asserted results in the switchable pass element being turned on, and vice-versa. A threshold selection and shaping circuit shapes the output regulated voltage or the dynamic threshold so that: (i) in response to assertion of the control signal, the difference between the dynamic threshold and the output regulated voltage is abruptly increased and subsequently gradually decreased towards a target static value, and (ii) in response to de-assertion of the control signal, the difference is abruptly increased and subsequently gradually decreased towards a target static value.
