The ISL9016IRUBWZ-T is a high-efficiency, quad-output integrated voltage regulator with a wide input voltage range of 3.5V to 28V. It is suitable for applications requiring multiple regulated voltage sources such as tablet PCs, digital cameras, portable media players, and automotive entertainment systems. This device provides up to four regulated outputs with an accuracy of ±0.5%. The outputs are adjustable via external resistors and its high power conversion efficiency makes it an excellent choice for applications where low power consumption is of utmost importance.

The ISL9016IRUBWZ-T integrates four linear voltage regulators, each capable of supplying up to 1.5A. The wide input voltage range makes it suitable for automotive applications where the input voltage can vary significantly due to engine start-up or other sources of input power. The device also provides short-circuit protection, under-voltage lock-out, current limiting, thermal protection, and EMI/EMC immunity. Furthermore, the device can be configured with up to four outputs. These outputs are adjustable via external resistors, allowing the flexibility to select a wide range of output voltages.

The working principle of the ISL9016IRUBWZ-T is relatively straightforward. The device consists of four independent linear voltage regulators, each with its own output voltage setting. These regulators work by comparing the output voltage to the reference voltage and driving an output transistor accordingly. If the output voltage is lower than the reference, the output transistor will turn on and increase the output voltage. Conversely, if the output voltage is greater than the reference, the output transistor will turn off, causing the output voltage to decrease. This regulation feedback loop is constantly regulated and this ensures that the output voltage remains within the required tolerance.

In summary, the ISL9016IRUBWZ-T is a high-efficiency quad-output integrated voltage regulator, suitable for a wide range of applications where accurate voltage regulation is required. It is easy to configure with its adjustable external resistors, allowing a wide range of output voltages. The device has built-in features such as short-circuit protection, thermal protection and EMI/EMC immunity, making it suitable for various applications. Finally, its working principle is relatively straightforward, comparing the output voltage to the reference voltage in order to drive the output transistor accordingly.
