Abstract: A linear regulator with an N-type pass transistor includes an over-current protection circuit. A current sink is used as an indicator for an over-current condition and is coupled to the output of the linear regulator. The indicator is coupled to a feedback logic circuit that controls the current through the output load. The over-current protection circuit extensively uses N-type devices for various components including the output driver stage in the circuit. This results in reduced area for the over-current protection circuit.

Abstract: Described herein are principles for designing and operating a voltage regulator that will function stably and accurately without an external capacitance for all or a wide range of load circuits and characteristics of load circuits. In accordance with some of these principles, a voltage regulator is disclosed having multiple feedback loops, each responding to transients with different speeds, that operate in parallel to adjust an output current of the regulator in response to variations in the output current/voltage due to, for example, variations in a supply voltage and/or variations in a load current. In this way, a voltage regulator can respond quickly to variations in the output current/voltage and can avoid entering an unstable state.

Abstract: An integrated Low Dropout (LDO) linear voltage regulator provides improved current limiting. A differential voltage amplifier compares an output voltage to reference voltage and controls a pass transistor to make the output voltage substantially match the reference voltage. This is accomplished by sensing the output voltage of the voltage regulator for application to a first input of the differential amplifier and coupling a second input of the differential amplifier to the reference voltage. A current sense transistor utilizes current mirroring techniques to sense the current passing through the pass transistor to the output. This sensed current is compared to a reference current. The result of that comparison is fed back to the differential voltage amplifier to in a manner that increases the apparently sensed output voltage in situations where the sensed current exceeds the reference current.
