Working Principles

The ADP2108AUJZ-2.3-R7 is a linear voltage regulator that uses a feedback mechanism to maintain a stable output voltage. It operates by comparing the output voltage with a reference voltage and adjusting the internal circuitry to regulate the output voltage at the desired level.

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