摘要： Provided is a voltage regulator in which an output current can be controlled stably and accurately to an overcurrent protection set value without the need of providing a phase compensation circuit including an element having a large area. The voltage regulator includes a constant voltage control circuit including: a first differential amplifier circuit for comparing a first reference voltage and a feedback voltage to each other; and an output transistor to be controlled by an output voltage of the first differential amplifier circuit, and an overcurrent protective circuit including: a resistor for measuring the output current; a second differential amplifier circuit for measuring a difference between voltages at both terminals of the resistor; a comparator for comparing an output voltage of the second differential amplifier circuit and a second reference voltage to each other; and a switch to be controlled by a detection signal of the comparator. When the output current equal to or larger than an overcurrent protection set value flows, the output voltage of the second differential amplifier circuit is input to the first differential amplifier circuit via the switch, to thereby switch control of the output transistor from control based on the constant voltage control circuit to control based on the overcurrent protective circuit.

摘要： A current detection resistance such as a metal resistance is formed in series with a power transistor, and in response to an output voltage of the current detection resistance, an overcurrent protective circuit performs an overcurrent suppressing operation with high accuracy without being affected by irregularity of a current multiplication factor, etc.; thus, it is possible to realize a smaller chip area so as to reduce the cost. Furthermore, a short-circuit protective circuit returns a terminal voltage of a referenced resistance, that appears in accordance with a partial pressure value of an output voltage, at the transistor, a partial pressure resistance, and a current mirror circuit. And the short-circuit protective circuit controls a potential of a base resistance and suppresses a base current. Hence, it is not necessary to dispose the transistor for suppressing a current between base lines, so that a low-voltage operation can be realized. In a direct-current stabilization power supply device having a two-chip structure of a PNP power transistor and a control IC, it is possible to achieve a smaller chip area and a low-voltage operation.

摘要： A voltage regulator circuit is described which includes a circuit input (48) and a circuit ouput for coupling to a load (74). A circuit interrupt element (82) is coupled between the input (48) and the load (74) for breaking the circuit between the input (48) and the load (74). A sensing circuit (76) between the input (48) and the output senses when a signal applied to the load (74) exceeds a defined limit. A trigger circuit (72) coupled to the sensing circuit (76) causes the circuit interrupt (82) element to trip when the sensing circuit (76) senses a signal which exceeds the defined limit.

摘要： The purpose of the present invention is to supply a method and a circuit simple and accurate enough to protect at least one transistor against exceeding a complex limit implying processing of multiple electrical quantities associated with said transistor.
Since in many practical cases said complex limit corresponds to the product of at least two quantities, typically a current and a voltage, the circuit in accordance with the present invention generates electrical signals basically proportional to said quantities, multiplies them, compares the product with a reference signal corresponding to the limit placed on the transistor and acts on the transistor in such a way that said limit is not exceeded.
Advantageously the multiplication of currents can be provided simply by means of connection in series of bipolar transistor junctions at which said currents are supplied to the respective emitters. In this case it is additionally advantageous to generate the reference signal by means of connection in series of the bipolar transistor junctions in such a manner as to have an analogous behaviour of the multiplier and the generator.
