Introduction

Linear voltage regulators, often referred to as PQ1R23, are an integral part of the power management integrated circuit (PMIC) family. Used in a variety of different applications, they provide a stable, regulated output voltage which is required to power a wide variety of semiconductor devices. In this article, we will discuss the application fields, working principle and key performance parameters of the PQ1R23 linear voltage regulator.

Application Field

The PQ1R23 linear voltage regulator is one of the most versatile voltage regulation components available. Common applications range from providing a stable power supply for a wide variety of electronic circuits, to providing power for automotive and other industrial applications. Due to its small size and low operating voltage, the PQ1R23 is often preferred for portable applications such as mobile phones and LED lighting.

Working Principle

The PQ1R23 linear voltage regulator works using a negative voltage feedback loop. When the output voltage exceeds the preset value, the regulator reduces the voltage, and vice versa. The circuit is made up of an internal reference voltage set by an adjustable resistor, which acts as the “setpoint” for the regulator. This setpoint can be adjusted to set the output voltage to the desired level.Another key feature of the PQ1R23 linear voltage regulator is its “low dropout” characteristics. This means that as the input voltage is lowered, the PQ1R23 maintains a constant output voltage level. This is one of the many characteristics of these regulators which makes them well-suited for portable applications where battery life is an issue.

Parameters

The PQ1R23 linear voltage regulator offers a wide range of performance parameters, including output voltage, current capacity, temperature range, and switching frequency. These parameters are important to consider since they will determine the efficiency and lifespan of the regulator. Output voltage is of particular importance and refers to the maximum output voltage that the regulator can provide, often up to 25 volts. Current capacity is another important parameter, referring to the maximum current that the regulator can supply, usually up to 3 amperes. The temperature range indicates the minimum and maximum temperatures at which the regulator can be operated without affecting its performance. Finally, the switching frequency determines how quickly the regulator can respond to changes in input voltage to maintain the setpoint output.

Conclusion

The PQ1R23 linear voltage regulator is an essential component of PMIC systems, providing a stable, regulated voltage which can power a wide variety of electronic devices. Its small size and low operating voltage make the PQ1R23 especially suited for mobile and portable applications. Key parameters to consider when selecting the PQ1R23 include output voltage, current capacity, temperature range, and switching frequency. With the right parameters, the PQ1R23 can ensure reliable power delivery for a wide range of applications.
