Working Principles
The ISL89164FBEAZ-T 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 control the pass transistor's conduction. When the output voltage drops below the desired level, the pass transistor conducts more current to increase the output voltage. Conversely, when the output voltage exceeds the desired level, the pass transistor conducts less current to decrease the output voltage.
