NCV4290DS50R4G Application Field and Working Principle

Introduction

NCV4290DS50R4G is a low voltage, low quiescent current linear voltage regulator (LVR) offering high voltage accuracy and tight load regulation for low power systems. With the features of low quiescent current of 140μA (typ.), low dropout voltage of 350mV (typ.) at 1A load, fast transient response time and 2% accuracy, the NCV4290DS50R4G is ideal for battery-operated systems, including mobile phones or personal digital assistants (PDAs).

Application Field

The NCV4290DS50R4G is a small form factor, low dropout regulator designed to support a wide range of loads, making it the ideal solution for battery-powered systems. It provides a high voltage accuracy of 1.69V to 5.0V at a load current of up to 1A. The device is capable of regulating output current beyond its rated limit and can operate over a temperature range of -40℃ to +85℃. Typical applications include battery operated consumer electronics, cellular phones, computing platforms and set-top boxes.

Working Principle

The NCV4290DS50R4G consists of an internal low dropout regulator (LDO) with a precision reference. The LDO is a three-terminal device consisting of a PMOS transistor and a voltage reference. When the input voltage (Vin) is greater than the output voltage (Vout), the PMOS transistor is turned on, allowing current to flow from Vin to Vout.The precision reference circuit provides a stable output voltage and will not require external compensation for most applications. The voltage reference is typically rated 2.5V and will adjust to compensate for temperature and load changes. In addition to a stable output voltage, the NCV4290DS50R4G incorporates reverse current protection, which prevents the device from being damaged in the event of a negative voltage transient.

Summary

The NCV4290DS50R4G is a low voltage, low quiescent current linear voltage regulator (LVR). It offers high voltage accuracy and tight load regulation for low power systems, along with a low dropout voltage of 350mV. Typical applications include battery operated consumer electronics, cellular phones, computing platforms, and set-top boxes. The device consists of an internal low dropout regulator (LDO) with a precision reference, a PMOS transistor, and a voltage reference. The precision reference circuit provides a stable output voltage, while reverse current protection prevents the device from being damaged in the event of a negative voltage transient.
