The NCV565D2T12R4G is a low-power linear voltage regulator designed to support voltage translation, as well as generating a single output voltage from an input voltage of up to 18V. The device boasts an ultra-low quiescent current of 1.74μA and offers a wide range of operating temperature ranges and voltage drop values, making it suitable for a variety of applications requiring reliable low-power operations.

Conceptually, a linear voltage regulator is a device that provides a constant, relatively low output voltage regardless of the voltage of its input, either higher or lower. The regulator achieves voltage regulation by means of series pass transistors that dissipate any excess energy as heat. While linear voltage regulation prevents any changes in the output voltage, the wastage of energy occurring with this design approach may be undesirable in some situations. The NCV565D2T12R4G is a great choice for such energy sensitive applications due to its remarkable low quiescent current.

The NCV565D2T12R4G part can be used for a variety of applications. It can regulate the output voltage of an A/C adapter, providing a constant output regardless of the fluctuations in the input voltage. It can also be used to protect upstream supplies, providing fail-safe protection for downstream components. Additionally, the NCV565D2T12R4G can be used to voltage translate, allowing two different voltage sources to be connected while maintaining a stable output. With its high efficiency and low quiescent current, the NCV565D2T12R4G is an ideal solution for a wide range of power requirements.

The internal structure of the NCV565D2T12R4G consists of an adjustable voltage reference, an error amplifier, and a series pass transistor. Together, these three components allow the device to maintain a stable output voltage in the presence of variation in the input voltage. The voltage reference, or reference voltage, is set by the external resistor divider and serves as the target voltage for the regulator. The error amplifier then compares the output voltage to the reference voltage, and controls the series pass transistor, thus regulating the output voltage. The series pass transistor dissipates any excess energy to maintain a stable output voltage.

The NCV565D2T12R4G is a great choice for applications requiring a reliable, low-power voltage regulator. It offers a wide range of operating temperature ranges and voltage drop values and boasts an ultra-low quiescent current. With its high efficiency and internal protection features, the NCV565D2T12R4G is an ideal solution for a wide range of power requirements.
