ABSTRACT:
A power-efficient power regulation circuit for use in semiconductor circuit powered by a power signal includes an N-channel transistor which provides a regulated power signal having a stabilized voltage level for use by the semiconductor circuit. A bias pull-up circuit is coupled to the gate of the N-channel transistor and arranged for biasing the N-channel transistor so that it normally conducts current, and a resistive circuit, including a resistive element arranged in series with a resistor-arranged P-channel transistor, is coupled to the source of the N-channel transistor and, in response to the regulated power signal, provides a feedback control signal. A voltage control circuit, coupled to the bias pull-up circuit and the resistive circuit, is activated to control the N-channel transistor in response to the feedback control signal. The voltage control circuit may include an enabling transistor which is activated to enable the voltage control circuit.
