Working Principle

The PQ1U321M2ZPH is a three terminal voltage regulator, with an input voltage, an output voltage and a control voltage. The input voltage is applied to the base of the control transistor, which causes current to flow from the control transistor to the output voltage. The two transistors then act as a voltage divider, with the output voltage being determined by the ratio of the two resistors. The control voltage is usually fixed, and is adjusted to regulate the output voltage.As the input voltage changes, the voltage across the two transistors changes. This change in voltage causes a current to flow through one of the transistors, while the other transistor conducts the supply current. This sets the output voltage, which is adjusted according to the control voltage. This arrangement of the two transistors allows the PQ1U321M2ZPH to be able to control the output voltage with a high degree of accuracy.

Conclusion

The PQ1U321M2ZPH is a linear voltage regulator from the PMIC family and is capable of providing a wide range of adjustable output voltages. It is used in a variety of applications, from automotive to microprocessor and communication applications. The PQ1U321M2ZPH is a 3 terminal regulator, and works by using two transistors to form a voltage divider. As the input voltage changes, the output voltage is adjusted according to the control voltage. With its high degree of accuracy, the PQ1U321M2ZPH is essential in providing reliable power to a variety of components.
