Overview
The NCV4274CDT50RKG is a precision micro-power voltage regulator produced by onsemi. This regulator is designed to provide an output current of up to 400 mA and is available in the DPAK package. It features an output voltage accuracy of ±2.0% and a maximum dropout voltage of 0.5 V with an input voltage range up to 40 V. The device is characterized by its low quiescent current, drawing only 125 µA at a 1 mA load, making it ideal for automotive and battery-operated microprocessor equipment. The regulator includes protections against reverse battery, short circuit, and thermal overload conditions, and it can withstand load dump transients, making it suitable for use in automotive environments.
