NCV2931AD is an industry-leading low-drop linear voltage regulators. It provides an adjustable output voltage from 1.2V to 5.0V, and a maximum output current up to 250mA of stable current. It supports a wide input voltage range of 2.5V to 8.0V, allowing for high efficiency operation with low output ripple

Application Field & Operating Principle

NCV2931AD-5.0R2 is suitable for applications requiring adjustable voltage in many markets, including communication, notebook computers, and other industrial Automation and consumer goods. It is also a low-cost linear voltage regulator that can be used in a wide variety of applications, such as general-purpose regulated or adjustable supply voltages, step-down dc-dc converters, high-current power supplies, and battery chargers.

The NCV2931AD-5.0R2 includes an internal pass transistor that adjusts the output voltage. The external feedback voltage divides the output voltage, and the error amplifier compares the two. The error voltage adjusts the output voltage according to design. The sense transistor ensures that the regulator output current will not exceed 250mA.

In addition, because the NCV2931AD-5.0R2 is designed with a floating configuration and current regulated output, the device is protected from short-circuit and open-circuit conditions. Other special features incorporated into the device include adjustable overtemperature protection, latch-off protection, and a current limit typ .8A.
