PQ070XZ5MZZH Application Field And Working Principle

Introduction

The PQ070XZ5MZZH is a three-terminal linear voltage regulator integrated circuit (IC) from Renesas Electronics Corporation. As a member of their voltage regulator family, the PQ070XZ5MZZH is part of the PMIC – Voltage Regulators – Linear lineup, with a wide range of input and output capabilities and types. For example, the PQ070XZ5MZZH has an input voltage range of 4.5V to 20V, with an output voltage range of 1.5V to 10V, which can be adjusted with an external divider. It is also capable of supplying up to 100mA, at an operating temperature range of -40°C to +85°C. Additionally, it uses a relatively low quiescent current, reducing power consumption when used in systems with limited power sources.

Application Field

Due to its large input and output range, combined with its low quiescent current features, the PQ070XZ5MZZH can be used in a wide range of applications. For example, it can be used in power-sensitive systems such as hand-held devices and battery-powered devices. Since it has an adjustable output voltage, long-term voltage stability and output voltage ripple, it can also be used to control and stabilize the supply voltage for chips and components in different electronic devices.The PQ070XZ5MZZH IC also has protection functions to protect the circuit from a wide range of external interferences. For instance, it has a built-in reverse bias protection, a current limit circuit, and an output short circuit protection. As such, it can greatly reduce the risk of damage caused by abnormal voltage, current and power levels.

Working Principle

The basic working principle of the PQ070XZ5MZZH is based on a voltage regulating circuit, which is composed of a series of resistors, transistors and other inertial components. Basically, an operational amplifier is used to compare the output voltage to a reference voltage, and then use the output of the amplifier to control the amount of current flowing through the system. When the output voltage is higher than the reference voltage, the operational amplifier will decrease the amount of current flowing through the system, which will cause the output voltage to drop. On the other hand, when the output voltage is lower than the reference voltage, the operational amplifier will increase the amount of current flowing through the system, which will cause the output voltage to rise. This mechanism is repeated in a continuous cycle, which serves to dynamically regulate the output voltage of the PQ070XZ5MZZH IC over time.

Conclusion

The PQ070XZ5MZZH is a three-terminal linear voltage regulator IC from Renesas Electronics Corporation. It is part of the PMIC – Voltage Regulators – Linear family and has a wide range of input and output capabilities. It can be used in many applications, such as hand-held devices and battery-powered systems, and also comes with protection functions to prevent damage caused by abnormal voltage, current and power levels. The basic working principle of the PQ070XZ5MZZH relies on a voltage regulating circuit, which uses an operational amplifier to compare the output voltage to a reference voltage and then use the output of the amplifier to control the amount of current flowing through the system.
