PMIC, or Power Management integrated circuits, are complex systems that regulate the power flow in a device or a circuit. Linear voltage regulators (LVRs) are one type of PMICs that provide a way to obtain a stable output voltage. PQ1R25J0000H is one such LVR device with a wide range of application fields and working principles.

Application Fields

The PQ1R25J0000H is a versatile linear voltage regulator that is well-suited for a wide range of applications. It has a very low dropout voltage and very low quiescent current, making it ideal for low power designs. It can be used as an adjustable voltage regulator, constant voltage source, or battery charger. It is also suitable for parts with a long standby current, such as power supplies for microcontrollers or ZigBee communication. Furthermore, its wide operating temperature range makes it suitable for applications in harsh environments, such as automotive, industrial, and medical applications.

Working Principles

The PQ1R25J0000H is a linear voltage regulator that can be used to adjust the voltage to the desired level. It is composed of a PNP and NPN transistor pair with an emitter follower circuit. The PNP transistor acts as an upper limit, while the NPN transistor acts as a lower limit. A voltage divider is used to determine the output voltage, and an operational amplifier is used to regulate the output voltage. With the help of a feedback loop, the internal circuit can maintain a corresponding output voltage as the input voltage changes. Additionally, the PQ1R25J0000H also has a built-in reverse current protection feature which prevents the flow of current backwards into the circuit.

In addition, the PQ1R25J0000H also has a built-in thermal protection feature, which can detect when the temperature of the part exceeds a certain point and shut off the output current. This ensures the safety of the part and the circuit in which it is used.

Conclusion

The PQ1R25J0000H is a versatile linear voltage regulator with a wide range of applications. It has a low dropout voltage and low quiescent current, making it suitable for low power designs. Additionally, its wide operating temperature range and built-in protection features make it suitable for applications in harsh environments. The PQ1R25J0000H can be used to adjust the voltage to the desired level, and has a feedback loop to maintain a corresponding output voltage even as the input voltage changes.
