NCV4279BD2R2 is a low dropout (LDO) linear regulator. It is specially designed for the purpose of energy saving. It features low quiescent current, low output voltage range and great power handling capability. It is ideal for point-of-load regulation, supplying VDC levels from 0.8V to 5.5V.

The main application field of NCV4279BD2R2 is in energy efficient, low voltage point-of-load applications. It is suitable for use in DC/DC converters, battery-powered applications and other power sensitive applications. For example, it can be used in remote control signals, radio communication, automotive infotainment systems, mobile phones/smartphones, GPS, and other portable and hand-held devices.

The working principle of NCV4279BD2R2 is relatively simple. It consists of a voltage regulator integrated with a control circuit, which maintains a constant output voltage. The input voltage is applied to the non-inverting input of the control circuit and the output voltage is applied to the inverting input. A potential divider is used to feedback a fraction of the output voltage, back to the control circuit. This regulation feedback loop constantly monitors the output voltage, and adjusts the output current as necessary to maintain the output voltage at a constant level.

The NCV4279BD2R2 also features an over voltage protection, which will shut down the output if the output voltage exceeds the set threshold. It also includes an output short circuit protection and an over-temperature shutdown. Additionally, it offers a wide input voltage range, low quiescent current, fast start up time, low output noise and a high operating temperature range. In summary, the NCV4279BD2R2 is a robust and energy efficient LDO linear regulator, ideal for a variety of power sensitive applications.
