Working Principles

The MCP1725-ADJE/MC operates as a linear voltage regulator. It takes an input voltage from the VIN pin and regulates it to a desired output voltage at the VOUT pin. The feedback (FB) pin is used to set the output voltage by connecting appropriate resistors. The enable (EN) pin controls the on/off state of the regulator.

When the input voltage exceeds the desired output voltage plus the dropout voltage, the regulator operates in a "dropout" mode, where it maintains a constant output voltage despite variations in the input voltage. The low quiescent current ensures minimal power consumption when the load is light.
