Self-initialized soft start for Miller compensated regulators

A Miller compensated voltage regulator, adapted to be supplied with power from a voltage supply, and having an input port and an output port, comprising:

• a voltage regulation circuit responsive to a reference voltage at the input port to provide a regulated voltage at the output port, comprising
• a current source adapted to be coupled to the voltage supply for supplying a predetermined current,
• a first input transistor and a second input transistor connected together as a differential pair to receive said predetermined current, said first input transistor having a gate for receiving an input reference voltage, said first input transistor and said second input transistor being connected to controlling circuitry for providing a regulated voltage at the output port,
• a current mirror comprising a first current mirror transistor connected between said first input transistor and a ground and a second current mirror transistor connected between said second input transistor and said ground, and
• a Miller compensation capacitor connected between the output port and an internal node comprising the common connection node of said first input transistor and said first current mirror transistor;
• and an enable control circuit, comprising
• an enable circuit responsive to an enable signal signaling a disable mode to prevent said current mirror from conducting current, and responsive to said enable signal signaling an enable mode to allow said current mirror to conduct current, and
• a delay circuit responsive to a transition in said enable signal from signaling said disable mode to signaling said enable mode, for maintaining said internal node at a high impedance with respect to the voltage supply for a predetermined interval.
