IRU1205CLTR Application Field and Working Principle

IRU1205CLTR is a kind of Linear Voltage Regulator (or regulator) which belongs to Power Management Integrated Circuits (PMIC). It can provide a constant and stable output to an electrical device, even though the input applied is varying. The device is ideally suited for power supplies and DC power conversion, and is also commonly used in applications such as laptop computers and other portable devices, providing a clean and reliable DC power to the load.

Overview

The IRU1205CLTR is a 3 terminal linear voltage regulator designed for use in a variety of applications where a stable, low noise output voltage is required. It is offered as an integrated solution with an integrated PMOS transistor, current-limiting resistors, and an N-channel MOSFET. This trademarked unit is designed to provide a reliable, low noise output voltage of up to 18 volts, with a maximum output current of 2.5 amps. It is offered in a package size of 4.7 mm (W) x 10.4 mm (L) x 1.7 mm (H).

Applications

The IRU1205CLTR is suitable for a wide range of applications, especially where reliability is essential. It can be used to provide a stable output voltage for a variety of power supplies, from laptop computers and other portable devices to industrial applications that require a reliable source of DC power. It is especially suited for low voltage, high current applications.

Features

The IRU1205CLTR features an input voltage range of 4.5V – 28V, an output voltage range of 4.5V - 18V, and a guaranteed output current of 2.5A. It also provides a wide temperature range of -40°C to +125°C. The combination of fast and accurate output voltage regulation, low noise operation, low input and output ripple, and low dropout voltage allow the regulator to provide a very clean and stable power to the load.

Working Principle

The IRU1205CLTR works on a simple concept. As the input voltage applied to the regulator increases, the output voltage will also increase. This is achieved by the use of two transistors, one of which is an N-channel MOSFET, and the other is an integrated PMOS transistor. The PMOS transistor acts as a current limiter, which limits the current that is supplied to the load. The N-channel MOSFET acts as an electronic switch, which turns on and off depending on how much power is required from the regulator. The N-channel MOSFET determines how much current is supplied to the load, and the PMOS transistor ensures that the voltage across the load remains constant. By carefully controlling the current and voltage, the regulator is able to provide a stable output, even in the presence of varying input voltages.

Conclusion

The IRU1205CLTR is an ideal choice for a variety of applications, especially where reliability is essential. It is a 3 terminal linear voltage regulator that offers simple, efficient, and reliable operation. It is also well-suited for low voltage and high current applications, providing a stable and reliable output. With its wide temperature range, low dropout voltage, low noise operation, and low input and output ripple, it is the perfect system for powering a variety of electronic devices.
