Working Principles

The AP1506-T5RG-U is a linear regulator that uses a pass transistor to regulate the output voltage. It operates by comparing the feedback voltage (FB) with a reference voltage, adjusting the pass transistor's resistance to maintain a stable output voltage. When the enable pin (EN) is high, the regulator is active, and when it is low, the regulator enters a low-power shutdown mode.
