Working Principles

The MAX502ACWG+ operates as a linear voltage regulator. It takes an input voltage within the range of 2.5V to 16V and regulates it to a stable and adjustable output voltage between 1.25V and 15V. The IC uses a feedback mechanism to compare the output voltage with a reference voltage and adjusts the internal circuitry to maintain the desired output voltage. It achieves high precision by utilizing a bandgap voltage reference and error amplifier.
