ON Semiconductor NCV4276DS33R4G Voltage Regulator

The ON Semiconductor NCV4276DS33R4G is a robust low dropout (LDO) voltage regulator designed to deliver a stable and reliable power supply. This particular model is engineered to output a fixed voltage of 3.3V, which is a common requirement for a wide variety of electronic devices and systems. With an output current capability of up to 750mA, it is well-suited for powering sensitive analog and digital circuits that require a clean and stable power source.

The NCV4276DS33R4G boasts a low dropout voltage, which ensures efficient operation even when the input voltage is very close to the output voltage. This feature is particularly beneficial in battery-powered applications where maximizing battery life is crucial. The device operates over a wide input voltage range from 5V to 45V, providing flexibility in a range of different circuit configurations and ensuring compatibility with various input sources.

Built with automotive applications in mind, the NCV4276DS33R4G is AEC-Q100 qualified, indicating that it meets the stringent requirements of automotive reliability standards. This makes it an ideal choice for use in vehicle power systems, including infotainment, navigation, and advanced driver-assistance systems (ADAS).

The device comes in a compact DPAK (TO-252) package, which is not only space-efficient but also allows for efficient heat dissipation. This packaging, combined with the built-in thermal shutdown and current limit features, protects the voltage regulator and its load from damage due to excessive temperature and overcurrent conditions. Additionally, the NCV4276DS33R4G includes a low quiescent current characteristic, which reduces power consumption when the device is in standby mode, further enhancing its suitability for power-sensitive applications.

For design flexibility, the NCV4276DS33R4G also features an enable function that allows the regulator to be turned on or off as needed. This can be used to reduce power consumption in systems where certain circuits only need to be powered at specific times.

In summary, the ON Semiconductor NCV4276DS33R4G is a reliable and efficient solution for a wide range of power regulation needs, especially in automotive and battery-operated applications where performance and durability are of paramount importance.
