Working Principles

The MAX154BENG operates as a linear voltage regulator. It takes an input voltage from the Vin pin and regulates it to provide a stable output voltage at the Vout pin. The adjustable output voltage is set using the Adj pin, which allows the user to select the desired voltage within the specified range.

The IC uses a feedback mechanism to compare the output voltage with a reference voltage. It adjusts the internal circuitry to maintain a constant output voltage despite changes in the input voltage or load conditions. This ensures a stable power supply for the connected electronic devices.
