Abstract:
A voltage regulator circuit disposed between a voltage source and a voltage drain, the regulator circuit comprising:a first current supplying transistor circuit disposed between the voltage source and the voltage drain, the first transistor circuit regulated by a voltage referenced control circuit selectively coupled to control a gate of the first transistor circuit;a voltage biasing control circuit coupled to the gate of the first current supplying transistor circuit, the voltage biasing control circuit adapted to provide a voltage bias to the first transistor circuit gate during power-up when the voltage referenced control circuit is electrically decoupled from controlling the first transistor circuit gate; anda second current supplying transistor circuit disposed between the voltage source and the voltage drain adapted to be regulated by the voltage referenced control circuit, the referenced voltage control circuit coupled to and continuously controlling the gate of the second transistor circuit to maintain a control loop for the voltage regulator circuit during power-up.
