Patent ID: 7928706

Claim:
A low dropout (LDO) voltage regulator comprising: a first multi-gate transistor having a first current electrode coupled to a first power supply voltage terminal, a first gate for receiving a reference signal, a second gate, and a second current electrode for providing a first current; a differential stage having a first terminal coupled to said second current electrode of said first multi-gate transistor, and a second terminal coupled to a second power supply voltage terminal, for selectively diverting said first current in response to a difference between a reference voltage and a feedback voltage to provide a voltage on an output terminal thereof; a second stage having an input terminal coupled to said output terminal of said differential stage, and an output terminal coupled to said second gate of said first multi-gate transistor; and a pass transistor having a first current electrode for receiving an input voltage, and a second current electrode for providing an output voltage, and a control electrode coupled to said output terminal of said second stage.
