Working Principle of AP7380-44W5-7

AP7380-44W5-7 is a linear voltage regulator, which is a voltage regulator providing an output voltage that is equal to or greater than its input voltage. It only works with an input voltage that is greater than the specified values. It does not increase the input voltage, so its output voltage depends on the input voltage.

In the simplest form, linear voltage regulation involves the use of a resistor and the input voltage is applied to the resistor in series with the output voltage. The output voltage is then determined by the voltage across the resistor, which is a function of its value. The regulator is used to maintain a constant output voltage by varying the resistor\'s value until the output voltage is equal to the desired value.

The AP7380-44W5-7 also features a low dropout (LDO) voltage regulator. It maintains the output voltage by adjusting the voltage across a series pass transistor, with the control voltage supplied by the output voltage. The LDO has a high input voltage tolerance, stable output voltage, and low noise.
