Working Principle
MPQ2013AGJE-33-C672-P is a linear voltage regulator. It works by comparing the output voltage to the reference voltage, and adjusting the current flowing through the pass transistor to maintain the output voltage. The reference voltage is generated internally by the circuit, and can be adjusted by an external resistor.
The pass transistor is the main component of the linear voltage regulator. It is operated in a linear region, where the current flowing through it is proportional to the voltage across it. The current is regulated by the error amplifier, which compares the output voltage to the reference voltage and produces an error signal. This signal is used to adjust the current flowing through the pass transistor so that the output voltage is kept at the desired value.
Another key component of the MPQ2013AGJE-33-C672-P is the over-temperature protection circuit. It monitors the device temperature and shuts the device down if the temperature exceeds the maximum limit.
Finally, the MPQ2013AGJE-33-C672-P also includes various protection features, such as short circuit protection, overtemperature protection, overvoltage protection, and reverse polarity protection.
Conclusion
MPQ2013AGJE-33-C672-P is a small size, high current output, linear voltage regulator suitable for portable devices, medical instruments and industrial equipment. Its primary components are the pass transistor and the error amplifier, which are used to adjust the current flow through the pass transistor to maintain a steady output voltage. The device also includes various protection features to ensure safe operation.
