Working Principles

The MAX6822MUK+T is a monolithic CMOS low dropout regulator (LDO). It regulates the output voltage by comparing the feedback voltage (FB pin) with an internal reference voltage. The error amplifier adjusts the pass transistor to maintain a constant output voltage despite variations in input voltage and load conditions. The enable pin (EN) controls the on/off state of the regulator.
