NCV4279D2R2 Application Field and Working Principle

The NCV4279D2R2 is a linear voltage regulator from ON semiconductors featuring full protection, a low quiescent current, adjustable output, and an input voltage of up to 5.5V. It is typically used for stabilizing voltage and current in industries, test and measurement equipment, laboratory equipment and automotive applications.

Application Fields of NCV4279D2R2

The NCV4279D2R2 is a linear voltage regulator with various features. It is designed to be used as an adjustable power supplies in industrial, test & measurement, automotive, home appliances and commercial applications. It can provide a regulated output voltage, ranging from 2V to 12V, and supply current up to 100mA. The device allows soft-start time and provides full transient protection and output current limiting. It also has thermal shutdown protection, so there is no need to worry about overburning or damage to the device.

Operating Principle of NCV4279D2R2

When an input voltage is applied to the NCV4279D2R2, the voltage regulator controls and maintains a constant output voltage by controlling the output current. This is done by comparing the input voltage and output voltage levels, and when the output voltage is lower than the input, the linear voltage regulator lets a controlled amount of current pass through it, thereby increasing the output voltage. When the output voltage is overall it limits the current passing through the device, maintaining a constant output voltage.The NCV4279D2R2 also has a back bias protection, with a fixed current limit of 1.5A, which is of great help in case of abnormal voltage supply or high input voltage. The device has built-in thermal shutdown that prevents the IC from being damaged due to excessive heat. The device also has low standby current, of maximum 20µA, which enables energy conservation.Because of its features, the NCV4279D2R2 is a great choice for automotive and test & measurement applications in which reliable power supply is very important. It also is well suited for a wide range of other applications such as industrial, commercial and home appliances, and can easily be integrated due to its SMD configuration. The NCV4279D2R2 is available in a Green SOIC-8 package.
