The NCV4269APD50R2G is a linear voltage regulator with fast transient performance and low dropout voltage. It is an low-input voltage, low-cost solution with very high power supply rejection ratio (PSRR) and low ground current. It is optimized for portable applications. This device is capable of providing up to a 1.65 A continuous output current.

The NCV4269APD50R2G is designed for Linear Applications. Linear applications use linear voltage regulators to stabilize the voltage of an electronic system, operating from a battery or other power source, without generating any noise created from a switching regulator. Linear regulators produce a steady output voltage from an input voltage that is usually higher than the desired output. Switched-mode power supplies (SMPS) are more efficient for higher voltage conversions, whereas linear regulators are the economical solution for lower voltage conversions.

The NCV4269APD50R2G includes internal thermal and current limit protection circuits to prevent damage in the event of over-current or over-temperature conditions, as well as an output disconnect function which disables the output during overload or short-circuit conditions.

When powered up, the NCV4269APD50R2G linear regulator operates in dropout mode, its output voltage being close to the input rail. In dropout mode, its output voltage is regulated by means of voltage error amplifier, nested feedback and other control circuits. Many designs use linear regulators to provide a fixed output voltage regardless of the load or input voltage. This avoids instabilities in the system and prolongs battery life.

The NCV4269APD50R2G is a versatile linear regulator which finds application in various fields. Low input voltage, high PSRR and a low dropout voltage limit makes it an ideal choice for portable systems, making it a preferred choice for designing devices like smartphones, tablets, PDAs and medical equipment. Its low ground current makes it a desirable choice for automotive applications such as audio systems and ECUs. Its low quiescent current and low dropout voltage make is suitable for battery powered applications like wearable devices, data loggers and remote monitoring systems.

The NCV4269APD50R2G serves as a low-cost, low-input voltage solution for linear voltage regulation applications.
