Working Principle of PQ20WZ5UJ00H

The basic working principle of PQ20WZ5UJ00H is the same as other linear voltage regulators. It utilizes a nonlinear control circuit to control the output voltage according to the input VIN, while maintaining excellent line-noise rejection, output accuracy, and fast response time.The circuit is composed of a voltage reference, an error-amplifier, a driver, and a series pass transistor. The voltage reference is responsible for providing a stable reference voltage for the error-amplifier’s input. The error-amplifier compares the reference voltage to the input voltage and amplifies the difference between the two. The driver takes the amplified error-voltage from the error amplifier, and passes it to the series pass transistor. The output voltage from the series pass transistor is then regulated according to the amplified error-voltage from the error amplifier.The input voltage (VIN) is then fed to the error-amplifier and the output voltage is regulated accordingly. The PQ20WZ5UJ00H linear voltage regulator offers high accuracy and very low output noise. It also has a very fast response time and is capable of providing good ripple rejection. It is therefore very suitable for a wide range of applications.

Conclusion

In conclusion, PQ20WZ5UJ00H is a high-efficiency linear voltage regulator module manufactured by Panasonic. It offers excellent accuracy, low noise, and fast response time, making it ideal for a variety of power management applications. Its working principle is based on a nonlinear control circuit which compares the input voltage to a voltage reference and uses an error amplifier to amplify the difference of the two. This amplified error is then used to control the output voltage accordingly. This ensures accurate, stable, and fast response output voltage.
