Working Principles

The MAX6390XS29D4-T is a voltage regulator that takes an input voltage range of 2.7V to 5.5V and provides a regulated output voltage of 2.9V. It achieves this by utilizing internal circuitry to maintain a stable output voltage, even when the input voltage fluctuates.

The device operates by comparing the feedback voltage (FB) with a reference voltage. If the output voltage drops below the desired level, the regulator adjusts its internal components to increase the output voltage. Conversely, if the output voltage exceeds the desired level, the regulator reduces the output voltage.
