• Dropout voltage of 200mV at 100mA may cause a significant power loss in low input voltage scenarios.

Working Principles

The SP6201EM5-L is a linear voltage regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB pin) with a reference voltage to adjust the pass transistor's resistance and maintain a constant output voltage. The enable pin (EN) allows for turning the regulator on or off.
