Working Principles

The ADP1715ARMZ-1.1-R7 operates as a linear voltage regulator. It regulates the output voltage by maintaining a constant voltage drop across its internal pass transistor. The feedback mechanism compares the output voltage with a reference voltage and adjusts the pass transistor accordingly to maintain the desired output voltage.

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