Working Principles

The MIC47100-08YMME is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB) with a reference voltage to control the pass transistor's conduction. By adjusting the resistance connected to the FB pin, the output voltage can be set to the desired level.

When the enable pin (EN) is high, the regulator is enabled, and the output voltage is regulated. If the EN pin is low, the regulator enters a low-power shutdown mode, reducing quiescent current consumption.
