The working principle of the NCP502SQ25T1G is based on a linear regulation design. When the input voltage is applied to the device, it will compare it to the output voltage on the bottom of the device and adjust the output voltage accordingly. To adjust the output voltage, the device will either increase or decrease the current through the pass transistor, depending on the difference between the input and output voltages. This type of control is called feed forward, which is the power control of the device. In addition, there is also the feedback control, where the output voltage is measured and compared to the set voltage. If the output voltage differs from the set voltage, then the control logic of the device will adjust the duty-cycle of the pass transistor in order to regulate the output voltage.

The NCP502SQ25T1G provides low-noise, low dropout and low quiescent current linear regulation in a variety of applications. It offers a wide range of features such as low output noise, high ripple rejection and low dropout voltage.
