Introduction

The NCV4949ADR2G is a standard linear voltage regulator from ON Semiconductor. This device is part of the industry-leading portfolio of Voltage Regulators from ON Semiconductor. The NCV4949ADR2G is a 4A low-dropout adjustable linear regulator. It provides low dropout and high accuracy. This device is well-suited for automotive and industrial applications as well as communications and computing applications.

Application Field & Working Principle

The NCV4949ADR2G is a versatile regulator that can be applied in a number of different ways. It is primarily used to power integrated circuits, but its adjustable output voltage range of 1.5V up to 22V makes it ideal for a variety of other applications. For example, it can be used to power LED drivers, motor drivers, and microcontrollers.The NCV4949ADR2G is a linear voltage regulator, which means it works by taking a higher input voltage and reducing it to a desired level. There are three pins on the regulator, the Input pin, the Output pin and the Reference (Adj) pin. The Input pin is connected to the higher voltage, the Output pin provides a regulated output voltage, and the Reference (Adj) pin is used to adjust the output voltage level.The NCV4949ADR2G is a low-dropout regulator, meaning the output voltage can be adjusted to nearly the same level as the input voltage, as opposed to regular regulators which require a higher input voltage. This is due to the low-dropout operation which enables the regulator to maintain regulation even when the input voltage is lower than the output.The NCV4949ADR2G also features protections against overvoltage, overcurrent and overtemperature. It has a maximum current suspension and dropout voltage of 5V and 1.2V respectively. It also has an adjustable current limit of 4A and requires a minimum current limit of 500mA.The NCV4949ADR2G is the ideal voltage regulator choice for applications and systems that require precision, reliability and flexibility. From simple LED drivers to more complex motor controllers and microcontrollers, the NCV4949ADR2G is up to the task.

Conclusion

The NCV4949ADR2G is a versatile linear voltage regulator from ON Semiconductor. It is suitable for a wide range of applications, from LED drivers to motor controllers and microcontrollers. It is a low-dropout regulator, meaning it can provide a regulated output voltage even when the input voltage is very low. The device also offers protections against overvoltage, overcurrent and overtemperature. For these reasons, the NCV4949ADR2G is an ideal choice for systems that require precision, reliability and flexibility.
