Specifications

The IRU1015CDTR output voltage linear regulator is a three-terminal monolithic integrated device that features low power dissipation, fast transient response, and wide output voltage range. It is capable of delivering up to 1.5A of continuous output current, with a wide output voltage range of 0.8V to 6.5V. The device has a minimum drop voltage of 2V, a maximum quiescent current of 5mA, and an operating temperature range of -40 to + 125°C.

Features

The IRU1015CDTR output voltage linear regulator features a low operating current of 5mA and a low EMI/RFI emission rate. It also features a Power Good signal which indicates when the device is operating within the set specifications. The device also offers overvoltage and overtemperature protection, as well as a thermal shutdown protection which shuts down the device when the temperature exceeds the safe operating range.

Working Principle

The IRU1015CDTR voltage linear regulator works by using an internal error amplifier to sense and compare the output voltage to a reference voltage. A feedback loop controls the current flow through the internal voltage divider. The amount of current flowing through the voltage divider determines the ratio of the output voltage to the reference voltage. This ratio is then used to control the output voltage. The output voltage is adjusted and stabilized to the desired levels by varying the voltage divider current.

Conclusion

The IRU1015CDTR output voltage linear regulator is a high performance, low power and low noise device designed to efficiently control and stabilize a wide range of output voltages. Its features include low power consumption, fast transient response, overvoltage and overtemperature protection, and a Power Good signal. The device works by using an internal error amplifier to sense and compare the output voltage to a reference voltage, and adjust and stabilize the output voltage by varying the voltage divider current.
