Overview
The ADP1290ACBZ-R7 from Analog Devices Inc. is a high-side power switch designed for efficient control of power in electronic systems. This device operates within a wide input voltage range of 2.3 V to 13.2 V and supports a continuous operating current of up to 2 A. It is particularly suited for battery-operated portable equipment due to its low quiescent current and ultralow shutdown current. The ADP1290ACBZ-R7 features a low on-resistance N-channel MOSFET, which minimizes power loss and provides power domain isolation, helping to extend battery life.
