Working Principles

The MAX1806EUA15+T is a low dropout linear voltage regulator. It regulates the output voltage by comparing the feedback voltage (FB pin) with a reference voltage. The enable pin (EN) controls the operation of the regulator. When the EN pin is high, the regulator is enabled and provides a regulated output voltage of 1.5V. Conversely, when the EN pin is low, the regulator is disabled, and the output voltage is not regulated.
