The ADM7155ARDZ-01-R7 is a reliable low power solution for consumer, industrial, and automotive applications. It can be used for powering FPGAs, DSPs, ASICs, and microprocessors. It is also suitable for use in medical devices, emerging Internet of Things (IoT), and battery-powered applications.

Wide Input Voltage Range

The ADM7155ARDZ-01-R7 has a wide input voltage range of 2.5V to 24V. This means that it can be used in systems that have different voltages depending on the system\'s specific requirements. It also has a low dropout voltage of only 0.2V, making it ideal for low power applications.

Protection Features

The ADM7155ARDZ-01-R also has integrated protection features such as over-current protection (OCP), short-circuit protection (SCP), and reversed battery protection (RBP). This makes it safe to use in a system where a fault can occur. These protection features also ensure that the device does not get damaged due to any unexpected events that may occur.

Tracking Accuracy

The ADM7155ARDZ-01-R has an excellent tracking accuracy of ±1.5%. This ensures that the amount of output voltage fluctuation remains low, allowing the system to maintain a stable performance at all times. The ADM7155ARDZ-01-R also has a low quiescent current, making it ideal for low power applications.

Working Principle

The ADM7155ARDZ-01-R works on a buck-boost topology. In this topology, the device takes an input voltage and steps it down to a lower voltage. The output is then regulated by a feedback loop that maintains a constant voltage and ensures stability. This makes it a reliable and efficient solution for low voltage applications.

Conclusion

The ADM7155ARDZ-01-R7 is an excellent choice for a low power step-down regulator. It has a wide input voltage range and excellent tracking accuracy. It also has integrated protection features for added safety. It is therefore ideal for use in consumer and embedded applications.
