Introduction

IRU1010CD is a linear voltage regulator from the family of integrated circuit voltage regulators. It is specifically designed for applications where low dropout voltage, low quiescent current, and protection against overheating are needed. The device has an adjustable output voltage controlled by an external resistor. It also provides a wide variety of protection features, such as thermal shutdown and current limit protection.

Applications

The IRU1010CD is primarily designed for use in battery operated systems where circuit protections are required. Its low quiescent current makes it suitable for portable applications. The low dropout voltage of the regulator and its adjustable output voltage makes it ideal for applications such as portable audio systems, PDAs, and communication equipments. Additionally, the IRU1010CD is also suitable for automotive applications, including Auxiliary Power Units (APUs) and Charging System Applications.

Features

The IRU1010CD has several features that make it an ideal choice for applications requiring circuit protection. It offers a low quiescent current of only 30uA and an adjustable output voltage range of 2.5V to 11.0V. The regulator has a low dropout voltage of only 1.2V and an operating temperature range of -40°C to 85°C. It also provides over-temperature, over-current and over-voltage protection.

Working Principle

The IRU1010CD is designed to regulate the input power supply voltage to a regulated constant output voltage. The regulator uses an internal high-gain operational amplifier to sense the input voltage. A control circuit within the device adjusts the input voltage so that the output voltage remain constant.The regulator also has a temperature protector, which prevents the device from being damaged due to sudden increase in junction temperature. When the junction temperature exceeds the specified level, the temperature protector stops the input voltage from reaching the regulator and turns off the device.

Package and Pinouts

The IRU1010CD is available in a variety of packages, including the 8-DIP and 8-SOP packages. The 8-DIP package contains the pins Layout C, while the 8-SOP package contains the Pin Layout A. The pin layouts are as follows:| Pin Layout A | Pin Layout C || ------------- | ------------- || VIN | VOUT || GND | GND || RS | NC || NC | NC || NC | VIN || NC | RS || NRST | NRST || NC | NC |

Conclusion

The IRU1010CD is a high-performance linear voltage regulator from the family of integrated circuit voltage regulators. It is specifically designed for applications requiring low dropout voltage, low quiescent current, and circuit protection. The device also incorporates several features such as adjustable output voltage and temperature protection. It is available in both 8-DIP and 8-SOP packages and is ideal for applications such as portable audio systems, PDAs, and communication equipments.
