Working Principles

The LM2705MF-ADJ operates as a step-down voltage regulator. It takes an input voltage from the VIN pin and regulates it to a lower, adjustable output voltage at the VOUT pin. The feedback (FB) pin is used to set the desired output voltage by connecting external resistors. The enable (EN) pin controls the regulator's on/off state.

When the EN pin is high, the regulator is enabled, and it starts regulating the input voltage to the desired output voltage. The internal circuitry of the LM2705MF-ADJ ensures efficient voltage conversion with minimal power loss.
