Working Principles

The 70V657S15DR is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB) with a reference voltage to control the pass transistor's conduction. The enable pin (EN) allows the user to turn the regulator on or off. When enabled, the regulator maintains a stable output voltage by adjusting the pass transistor's resistance to compensate for changes in input voltage and load conditions.
