摘要： A conversion apparatus including a plurality of high-speed switching devices (51-56), each being operable in latch type operation and non-latch type operation and a power source (1) for supplying a first current to the high-speed switching devices (51-56), thereby forming a current path of the high-speed switching devices (51-56). The high-speed switching device is turned off after changeover from the latch type operation to the non-latch type operation. The conversion apparatus further includes a current regulation circuit (30) provided in the current path for regulating a second current flowing through the current regulation circuit (30) from a time when the second current reaches a prescribed value. In a case of overcurrent malfunction, the high-speed switching device is changed from the latch type operation to the non-latch type operation, and then is caused to be turned off during when the current regulation circuit regulates the second current.

摘要： An automotive voltage regulator is disclosed to have plural regulated outputs using a transient protected isolator output stage (TPIOS) that prevents a system fault condition on any one output from adversely affecting the other outputs. In an automotive environment employing a nominal 14-volt supply, an individual output can be taken fron -4 to +26 volts without causing damage or having any significant reaction on the non-faulted outputs. The circuit employs a relatively small NPN output pass transistor and, therefore, requires a relatively low value stabilizing bypass capacitor.

摘要： A concentric collector PNP transistor is utilized in electrical circuits to determine when the voltages of different parts of a circuit are very close to each other. The transistor has an emitter zone, an inner collector zone that surrounds the emitter zone and an outer collector zone that surrounds both the emitter zone and the inner collector zone. When the voltage of the emitter is slightly higher than the voltage of the inner collector a signal is developed at the outer collector which is used as a trigger or control signal. An oscillator-voltage doubler circuit and a series pass voltage regulator circuit are disclosed that utilize the concentric collector transistor.

摘要： In a power supply control apparatus (11), a control circuit (23) adjusts a resistance between a drain and a source of a semiconductor transistor (20) by adjusting the voltage at a gate of the semiconductor transistor (20). After the control circuit (23) has lowered the resistance between the drain and the source, a control portion (56) determines whether or not the voltage at the source detected by a voltage detecting portion (21) is larger than or equal to a standard voltage. If it is determined by the control portion (56) that the voltage at the source is larger than or equal to the standard voltage, the control circuit (23) again lowers the resistance between the drain and the source. If it is determined by the control portion (56) that the voltage at the source is smaller than the standard voltage, the control circuit (23) adjusts the resistance between the drain and the source to a resistance at the time when determination was performed or larger.

摘要： A low-dropout voltage regulator comprises an output terminal for providing an output voltage regulated as a function of a reference voltage, and for providing an output current, and additionally comprising an output current limiting unit. The current limiting unit comprises a replicator for replicating the output current to provide a mirror current of the output current, a comparator circuit for comparing the mirror current with a reference current, and a feedback circuit for supplying feedback to the regulator in order to limit the output current when the mirror current is greater than the reference current. The mirror current is injected into the output terminal.

摘要： Circuits and methods for providing short-circuit protection in a voltage regulator are disclosed. A voltage regulator includes a pass switch, a voltage error amplifier, a driver circuit, and a short-circuit protection circuit. The pass element is coupled to a power supply and a load, and generates an output voltage in response to a drive signal. The voltage error amplifier generates an error voltage based on a difference of a reference voltage and the output voltage and the driver circuit generates the drive signal in response to the error voltage. The short-circuit protection circuit senses the drive signal and provides a high-resistance path to the driver circuit in a short-circuit event. In a short-circuit event, the high-resistance path clamps current in the driver circuit thereby clamping a voltage difference between the first and third terminals and thereby limiting a load current in the short-circuit event.

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.
