The IRU1117-25CDTR has been designed for use as a regulator for a range of commercial, industrial and automotive applications that require a robust linear voltage regulator. The device offers a 3.2V to 4.2V input voltage range and a 5V to 20V output voltage range. It has a 0.675V reference voltage and provides up to 1.4A of output current. The regulator has an Ultra-Low Dropout (ULDO) and can run at light load currents of 10mA.

The IRU1117-25CDTR is a linear voltage regulator that utilizes a two-stage, positive output LDO regulation architecture. In this design, the voltage feedback loop is set up to sense the output voltage and to adjust the feedback signal in order to maintain regulation of the output voltage. The input voltage is supplied to the regulator, the feedback signal is compared to a 0.675V reference voltage, and then the output voltage is adjusted accordingly. This ensures that the output voltage of the regulator is stable and accurate, even when the input voltage fluctuates or drifts.

The IRU1117-25CDTR is designed to have a wide operating temperature range of -40°C to 85°C with a maximum junction temperature of 125°C. Its current limiting and thermal shutdown features help protect the device from over-current and over-temperature faults. The internal power dissipation of the device is minimized by an efficient heat sink. To ensure electrical safety, the device is rated for an Input-Output differential of 3V, and a minimum input current of 2A.

The IRU1117-25CDTR has an excellent output ripple rejection of greater than 50dB at 1kHz, which enables smooth and efficient performance while meeting the EMI requirements of most systems. The device is also provided with an EMC filter to further enhance its performance in EMI-sensitive applications.

The IRU1117-25CDTR can be used in a wide range of applications that require a reliable and accurate voltage regulator. It is suitable for use in automotive, industrial and consumer electronic applications. It is also suitable for use in low-power, high-current switching power supplies, and can be used to provide regulated, low-noise power for sensitive ICs and ASICs.

Overall, the IRU1117-25CDTR is a high-performance, low-cost linear voltage regulator that is designed to provide reliable and accurate voltage regulation with low power dissipation. Its wide input range and excellent output ripple rejection make it an ideal solution for many commercial, industrial and automotive applications.
