The NCV4274ADT50RKG is an integrated low-dropout (LDO) voltage regulator manufactured by ON Semiconductor. It is a low-power, low-noise, highly efficient, and easy to use device. This device includes an input voltage range from 1.8 to 5.5V and outputs a maximum load current of 400mA. It has an adjustable output voltage ranging from 0.8 to 5V, and a dropout voltage of only 250mV at max current. It also includes thermal protection, current limitation, and reverse current protection to ensure that the device is always protected. This device is ideal for use in integrated circuit solutions, portable electronics, power supplies, and in analog signal chain applications.
