Introduction
PQ20WZ51J00H is a linear voltage regulator designed to control and supervise a variety of power supplies. It is particularly suitable for applications in which a relatively small current is required to maintain proper voltage control. It controls output voltage levels within preset ranges, while providing thermal protection and continuous current limiting protection.Application Field of PQ20WZ51J00H
The PQ20WZ51J00H Voltage Regulator is often used in applications where a small current is necessary to provide the best possible voltage control over varying load conditions. Examples of applications with such load conditions include automotive, appliance, and telecom systems.The device also features a low dropout voltage, up to 1.8V for a 5V load, so it is well-suited for highly efficient power supplies with limited power margins. This pin-to-pin compatible linear voltage regulator also features a wide input voltage range of up to 20V, allowing source voltages to fluctuate while keeping the output precisely regulated.Features of PQ20WZ51J00H
PQ20WZ51J00H provides a variety of features, such as low dropout voltage, fast transient response, supply current of 5.5mA, and protection against reverse current, thermal shutdown protection, and continuous over current protection.The main features of the linear PQ20WZ51J00H regulator are listed below:- Input voltage range: 5.5V to 20V
- Output voltage accuracy: ±2%
- Low supply current: 5.5mA
- High transient response (40 kHz) with low output voltage ripple
- Excellent PSRR (80 dB) and high CMRR (82 dB)
- Low drop-out voltage: 1.8V for 5V load
- Reverse current, thermal shutdown protection and continuous over current protection
- Pin-to-pin compatible
Working Principle of PQ20WZ51J00H
The PQ20WZ51J00H linear regulator operates on the principles of comparing input and output voltage levels. The input voltage is regulated by switching on the pass transistor, which allows current to flow from the input to the output.In order to maintain a stable output voltage, a feedback system is employed which monitors the output voltage at all times. This feedback loop adjusts the on/off time of the pass transistor as needed to ensure that the output voltage is consistent.The output voltage remains constant during dynamic load conditions , even when the load is changed rapidly. The PQ20WZ51J00H also provides protection for the device by incorporating features such as reverse current, thermal shutdown protection and continuous over current protection.Conclusion
The PQ20WZ51J00H is a linear voltage regulator designed to provide voltage control in applications requiring a small current. It features input voltage range up to 20V, with ±2% accuracy, as well as low supply current, fast transient response, high PSRR and CMRR, and protection for reverse current and thermal shutdown. The PQ20WZ51J00H’s feedback system provides precise control of the output voltage during dynamic load conditions, and the linear regulator is pin-to-pin compatible, making integration into any system straightforward.The specific data is subject to PDF, and the above content is for reference
