Working Principle

The ADP160ACBZ-3.3-R7 is a linear voltage regulator containing a power transistor and voltage reference. When the input voltage is higher than the output voltage, the power transistor is connected in series between the input and the output and a voltage control loop adjusts the duty cycle of the switch in order to maintain the output voltage. The resistance of the power transistor provides the feedback mechanism, adjusting the duty cycle to maintain the correct output voltage. The voltage reference is used to limit the output current and to sense the output voltage.

The power transistor is connected to the input voltage, while the voltage reference is connected to the output voltage. When the input voltage is higher than the output voltage, the power transistor is switched on and off, with the duty cycle adjusted to maintain the output voltage. This is done by adjusting the time the transistor is on and off in order to regulate the output voltage. When the power transistor is on, current flows from the input to the output, charging up the output capacitor and providing the output voltage. When the power transistor is off, the output voltage is maintained by the output capacitor discharging through the load.

The ADP160ACBZ-3.3-R7 is a low-dropout regulators, meaning the input voltage must only be slightly higher than the output voltage for it to regulate correctly. This makes it ideal for battery-powered systems, as the battery can slowly discharge while still maintaining the correct output voltage.
