The NCV47411PAAJR2G is a dual-channel low dropout (LDO) linear voltage regulator manufactured by onsemi, engineered specifically for harsh automotive environments with AEC-Q100 qualification. This device provides a regulated output voltage of 100mA per channel with an adjustable output range spanning 3.3V to 20V, offering exceptional flexibility for diverse power rail requirements. The regulator achieves a dropout voltage of 250mV while maintaining 3% output voltage accuracy through precision on-chip trimming of the reference voltage. Housed in a compact 14-pin TSSOP surface-mount package with an operating temperature range of -40°C to +150°C, this automotive-grade device incorporates comprehensive protection features and is supplied in tape-and-reel packaging (R2 suffix) for automated assembly in modern vehicle electronic systems.
The NCV47411PAAJR2G serves as a critical power management component in automotive body control modules, instrument clusters, and infotainment systems where multiple regulated voltage rails are required from a single battery input. It provides clean and stable power for microcontrollers, sensors, CAN transceivers, and analog signal conditioning circuits in engine management systems, transmission controllers, and advanced driver assistance systems. The dual-channel architecture with adjustable outputs makes it particularly valuable in gateway modules and domain controllers that must supply different voltage levels to various subsystems while maintaining automotive-grade reliability and diagnostic capabilities throughout extended temperature operation.
FAQs
Q: What is the maximum output current per channel?
A: Each LDO channel delivers 100mA continuous output current, with adjustable current limiting providing protection against overload and short-circuit conditions.
Q: Can the two channels operate at different output voltages simultaneously?
A: Yes, the dual channels are independently adjustable from 3.3V to 20V using separate external resistor dividers, enabling different voltage rails for mixed-voltage systems.
