PMIC - Voltage Regulators - Linear

PQ015ENA1ZPH is an advanced linear voltage regulator that is capable of efficiently delivering low output voltages ranging from 0.9V to 6V and capable of driving up to 1.5A of load current which makes it ideal for up-scaling a wide range of power systems. This voltage regulator provides a low noise solution to power management applications such as microprocessors, DDR memory, battery chargers, interface power supply, mobile handsets and other types of consumer product power supply applications.

Application Field

PQ015ENA1ZPH voltage regulator is highly versatile and suitable for a wide range of low voltage, low current applications. It provides excellent output voltage accuracy and fast transient response at very low quiescent current making it ideal for power management applications in portable and automotive devices. In addition, it provides short circuit protection and thermal protection which makes it suitable for industrial and laptop computers applications.

Working Principle

PQ015ENA1ZPH voltage regulator uses a closed-loop, fixed frequency, pulse-width modulation control scheme to maintain a constant output voltage under different load conditions. The output voltage is adjusted by the error amplifier which accurately senses the output voltage and regulates the current passing through a power MOSFET. The error amplifier also provides over-voltage protection, current limit protection, and thermal protection by shutting off or limiting the output voltage when an over-current or over-temperature condition is detected.

The adjustable potentiometer allows the user to fine-tune the output voltage and the standby mode allows for reducing quiescent current to levels as low as 0.25μA when the regulator is not required. The PQ015ENA1ZPH is designed to exceed the demands of the conventional applications and provide the highest level of performance and long-term reliability.

Conclusion

To conclude, PQ015ENA1ZPH voltage regulator is a very efficient and versatile linear voltage regulator that can be used in a wide range of power management applications. It provides excellent output voltage accuracy, fast transient response and short circuit protection. Its adjustable potentiometer and low quiescent current in standby mode makes it ideal for consumer and industrial applications.
