The NCV4276A DT ADJRKG is a low voltage single output adjustable linear regulator used for a wide range of low power applications. It offers one adjustable output with a maximum load current of 250 mA, a wide operating temperature range of -40 °C to +125 °C, and a maximum input voltage of 28 V. The output voltage can be adjusted from an ultra-low 0.8 V up to a maximum of 20 V, with excellent regulation characteristics and thermal performance.

As a linear regulator, the NCV4276A DT ADJRKG uses the process of establishing a stable operating voltage by regulating fluctuations in current input. Its working principle is to control the drop in voltage between the input voltage source and the output voltage regulator. This is achieved via a pass transistor that has two reference voltage sources, one on each side of the transistor. A feedback loop is used to monitor the output voltage, and the transistor adjusts its impedance in accordance with the voltage difference between the two reference voltage sources. In the event that the input voltage is higher than the output voltage, the internal pass transistor will be driven into conduction until the output voltage reaches the desired value. This closed loop control makes the voltage regulator capable of providing improved load and line regulation.

The NCV4276A DT ADJRKG is commonly used in battery-powered consumer electronics, such as mobile phones, digital cameras, and PDAs. It is also suitable for other low power applications like off-line power supplies, industrial circuits, and microprocessor power supplies. The excellent line and load regulation and thermal stability make the NCV4276A DT ADJRKG an ideal voltage regulating choice for many low power applications.
