Working Principles

The MC33152VDR2G is a voltage regulator that maintains a stable output voltage regardless of variations in the input voltage or load conditions. It achieves this by comparing the feedback voltage at the FB pin with a reference voltage, adjusting the pass transistor's resistance accordingly. This feedback loop ensures that the output voltage remains within the desired range.

When the enable (EN) pin is high, the regulator is active, and the output voltage is regulated. Conversely, when the EN pin is low, the regulator enters a low-power standby mode, reducing power consumption.
