Introduction to IRU1010-25CP

The IRU1010-25CP is a voltage regulator that belongs to the PMIC (Power Management Integrated Circuits) group, linear subgroup. It is particularly useful as it provides a pre-regulated voltage output for different industrial applications whether digital point-of-use, battery or other AC/DC power sources.

Application Field of IRU1010-25CP

The IRU1010-25CP is suitable for a wide range of applications including computers, handheld devices and communications. As such, it is often employed to provide regulated output inLED displays, electrical motors, digital servo drives, medical electronics, battery-powered devices, smartcard readers, and other industrial features.

The regulator is available in two versions: the standard and the SLG versions. The standard version is suitable for applications that require steady-state output current levels of 1.25A or less, while the SLG version provides efficient compensation over a wide temperature range, making it suitable for applications that require greater levels of output.

The IRU1010-25CP is an ideal regulator for use in harsh environments that demand high reliability and stability. It features an input range of 4.1V to 50V, an output voltage range of 0.8V to 28V, an adjustable output current up to 5A, a low drop-out voltage, and low quiescent current (IQ) rating.

Working Principle

The IRU1010-25CP utilizes a combination of a control stage and an error amplifier in order to regulate an output voltage. The control stage compares the reference voltage with an external provided feedback voltage, while the error amplifier measures the difference between the reference and the feedback voltages and amplifies it.

The control stage and the error amplifier work in tandem to achieve the required output voltage. When the output voltage dips below the required level, the control stage decreases the current to the error amplifier, thus decreasing the voltage of the output. In contrast, when the output voltage is higher than the desired level, the current to the error amplifier is increased, resulting in an increased output voltage.

The IRU1010-25CP is also capable of providing a fixed output voltage in the case of a fixed reference voltage. In this case, the control stage will still regulate the current to the error amplifier, but the output voltage will remain constant.

Conclusion

The IRU1010-25CP is an excellent regulator for harsh, industrial applications, offering high reliability and stability, an adjustable current up to 5A, and a wide temperature range. It utilizes a combination of a control stage and an error amplifier in order to regulate an output voltage, and is available in two versions: the standard and the SLG versions. This makes it an ideal choice for computers, handheld devices and communications, as well as other applications.
