Working Principles

The MIC2755BMM operates as a linear voltage regulator. It regulates the output voltage by maintaining a constant voltage drop across its internal pass transistor. The feedback pin (FB) compares the output voltage to a reference voltage (VREF), and any deviation is corrected by adjusting the pass transistor's resistance. This feedback loop ensures a stable output voltage regardless of variations in input voltage or load conditions.
