Working Principles

The MAX761CPA is a voltage regulator that operates based on the principle of a linear regulator. It regulates the output voltage by dropping the excess voltage across its internal pass transistor, resulting in a stable and regulated output voltage. The dropout voltage is the minimum voltage required for the regulator to function correctly.
