NCV4263-2CPD50R2G

The NCV4263-2CPD50R2G is a low drop-out linear regulator (LDO). It is a three-pin regulator device which supports an output voltage between 2.7V and 5.5V. It is designed to address the needs of battery powered systems, such as cellular phones, portable gaming devices and other applications which require good regulation with low quiescent current.

The NCV4263-2CPD50R2G operates by providing a regulated output voltage (VOUT) which is determined by the voltage applied to its feedback input, VFB. This voltage is inverted and filtered by a power stage circuit and compared with a reference voltage by an error amplifier. The output of the error amplifier is applied to an impedance stage, whose output signal is used to activate the MOSFET and limit the output current. The LDO’s output voltage is maintained by controlling the amount of current that the MOSFET can draw from the input supply. This is achieved by adjusting the MOSFET’s gate voltage which is set by the bias voltage on the VBIAS pin.

The NCV4263-2CPD50R2G is protected against in-rush current, over-voltage, and over-temperature conditions. Its constant current limit reduces the power dissipation in the regulator, improving overall efficiency and extending the battery life of the system. The wide input voltage range of 2.5V to 6.0V and the very low drop-out voltage make the NCV4263-2CPD50R2G well suited for a wide range of battery-powered applications.

In summary, the NCV4263-2CPD50R2G provides a wide range of features and benefits suitable for various battery-powered applications, while maintaining high performance, accuracy, and robustness. It is an ideal device for providing regulated output voltage in battery-powered applications such as cellular phones, portable gaming devices, and other point-of-load (POL) power supplies.
