The NCV4274AST33T3G is a precision micro-power voltage regulator from On Semiconductor, part of the NCV4274A series. It provides a fixed 3.3V output voltage with an accuracy of ±2.0% or ±4.0% and an output current capability of up to 400 mA. The device features a low quiescent current of 150 µA at a 1 mA load, making it suitable for battery-powered applications.
Designed for automotive environments, this regulator includes comprehensive fault protection, such as reverse battery, short circuit, and thermal overload protection. It can also withstand load dump transients and features a peak transient input voltage rating of +60V and a reverse voltage rating of -42V. The very low dropout voltage is also a key characteristic.
This component is available in a SOT-223 (TO-261) surface-mount package, facilitating integration into compact designs. Its operating temperature range is -40°C to 150°C (TJ). The NCV prefix indicates suitability for automotive applications requiring unique site and control change requirements, with AEC-Q100 qualification and PPAP capability.
Key electrical specifications include a maximum input voltage of 40V, a typical dropout voltage of 1.27V at 250mA, and a PSRR of 60dB at 100Hz. These features make the NCV4274AST33T3G a robust choice for reliable power management in demanding applications.
