Introduction: MPQ2013AGQ-25-Z is a three-terminal adjustable positive voltage regulator. It offers solutions for a output voltage range of 1.25V to 20V and current up to 1.5A. It requires only two external capacitors to deliver these features in a very space-saving SOT-223 package.

Application Field: MPQ2013AGQ-25-Z is suitable for various kinds of applications such as a DC/DC converter, a low power supply application, a battery-operated applications and other general purpose.

Working Principle: MPQ2013AGQ-25-Z consists of two main parts: the Voltage Programming Terminal and the Feedback Terminal. The voltage programming terminal is used to adjust the output voltage range linearly over a range of 1.25V to 20V. The feedback terminal provides the voltage feedback of the output voltage. The MPQ2013AGQ-25-Z utilizes an error amplifier, an internal voltage reference and a linear regulator to operate with stable operation.

Voltage Regulation: The output voltage of the MPQ2013AGQ-25-Z can be set by two external components: the program resistor, RP, and the feedback resistor, RF. The RP resistor sets the output voltage in order to create a voltage drop across the feedback resistor, RF (VOUT = VREF + VFB). The output voltage can be adjusted linearly between 1.25V and 20V.

Stability: The stability of the MPQ2013AGQ-25-Z is ensured by the use of two external capacitors. The input capacitor, CI, must have a low ESR (equivalent series resistance). The output capacitor, CO, must have a low ESR and a large electrolytic value. The external capacitors help to ensure that the output voltage is stable and regulated over a large range of temperature and load variations.

Protection: The MPQ2013AGQ-25-Z provides both over-current and over-temperature protection. The device will shut down if the output current exceeds a specified value or if the temperature exceeds the maximum specified temperature.

Conclusion: The MPQ2013AGQ-25-Z is a 3-terminal adjustable positive voltage regulator suitable for various kinds of applications. It provides a wide output voltage range, stable output voltage and current, and protection features. The device requires only two external capacitors to operate, thus making it very space-saving and efficient.
