NCP717CMX150TCG Application Field and Working Principle

NCP717CMX150TCG is a positive voltage regulator manufactured by ON Semiconductor. It is a low dropout (LDO) voltage regulator with 150mA output current. It is usually used in power management applications that require low noise and high accuracy output regulation. The device works on the principle of negative feedback, to provide voltage regulation and ensure a stable output voltage and low output noise.

The input of the NCP717CMX150TCG regulator is usually connected to the unregulated voltage from the power supply. This voltage is monitored by the internal circuitry and compared to the internal reference voltage of 1.227 volts. If the measured voltage is lower than the reference, then the internal circuitry reduces the current to the output. If the measured voltage is higher than the reference, then the internal circuitry increases the current to the output. This regulation is achieved through the use of an internal PNP transistor, which is activated if the measured voltage is higher than the reference.

The NCP717CMX150TCG device also includes many features that enhance performance and safety. These features include protection against over-voltage, reverse current protection, and thermal shutdown protection. In addition, the device supports external shutdown and can operate in a variety of power supply configurations.

Applications

The NCP717CMX150TCG is ideal for applications requiring low noise, high accuracy output regulation. It is typically used in power management systems, where high accuracy and low voltage noise is required. These applications include digital TVs, DVD players, gaming consoles, and cellular phones, as well as laptop computers, PDAs, power supplies, and automotive devices.

The NCP717CMX150TCG is also well-suited for battery-operated systems such as portable medical instruments and remote control systems.
