Working Principles

The MIC2285AYMT-TR is a linear voltage regulator that uses a pass transistor to control the output voltage. It operates by comparing the feedback voltage (FB) with a reference voltage (VREF). When the output voltage drops below the desired level, the regulator adjusts the pass transistor to increase the output voltage. Conversely, if the output voltage exceeds the desired level, the regulator reduces the pass transistor's conduction to lower the output voltage.
