The NCP4625DSN28T1G is a linear voltage regulator manufactured by ON Semiconductor. It is part of the company’s NCP42xx and NCP46xx series of voltage regulators. The device has a high current capability, low dropout voltage, and low quiescent current. As part of the NCP42xx and NCP46xx series, it offers high accuracy, low noise, and fast transient response. The NCP4625DSN28T1G is a positive voltage regulator that uses an adjustable or fixed output voltage setting. It operates at a maximum input voltage of 28 V and an output current of up to 1.8 A. The device features an adjustment pin that is used to set the output voltage in the adjustable output voltage version. It also features an enable pin which can be used to control the output state of the device.

The NCP4625DSN28T1G is commonly used in applications that require a high current output voltage with a low dropout voltage. It is suitable for use in switching power supplies, notebook computers, and other portable electronic devices that require a stable output voltage. It can also be used in battery-powered systems and other applications that require a low voltage output. The device can be used in both step-down and step-up applications. Its low quiescent current make it ideal for battery-powered applications.

The NCP4625DSN28T1G is based on an internal linear voltage regulator that is composed of two pnp transistors and two npn transistors. The regulator is a two-transistor feedback circuit that is operated in a closed loop to maintain a precise output voltage. The device is designed to provide an output voltage that is inversely proportional to its supply voltage. The output voltage is adjustable by changing the setting of the adjustment pin. The device also features an enable pin that can be used to turn it off or on. When the enable pin is asserted, the device is enabled and the output voltage is held at the set value.

In applications where high accuracy is required, the NCP4625DSN28T1G can be used with an external reference voltage. This will allow for an even more precise output voltage with minimal variation. The device also offers protection against over-current, over-voltage, and reverse-current conditions. It has a logic-controlled shutdown mode that disables the output when the enable pin is low.

The NCP4625DSN28T1G is a versatile and reliable voltage regulator solution for a variety of applications. It offers a high current capability, low dropout voltage, and low quiescent current, making it ideal for use in battery-powered systems. Its high accuracy, low noise, and fast transient response make it suitable for use in switching power supplies, notebook computers, and other portable electronic devices. The NCP4625DSN28T1G is an excellent choice for applications that require a high current output voltage with a low dropout voltage.
