NCV8114ASN120T1G: A 120 mA, 45 V Low Quiescent Current LDO Regulator from onsemi

In the realm of power management, efficiency and reliability are paramount, especially in automotive and industrial applications where conditions are harsh and demands are high. Addressing these needs, onsemi introduces the NCV8114ASN120T1G, a high-performance low-dropout (LDO) voltage regulator engineered to deliver exceptional performance under challenging conditions.

This regulator stands out with its impressive 45 V maximum input voltage rating, making it exceptionally robust against high-voltage transients commonly encountered in automotive environments. Despite this high voltage capability, the device maintains a remarkably low quiescent current (IQ) of just 16 µA typical under light load conditions. This low IQ is crucial for modern vehicles and battery-powered systems, where minimizing standby power consumption is essential for extending battery life and meeting stringent energy efficiency standards.

The NCV8114ASN120T1G provides a stable output current of up to 120 mA, sufficient to power critical low-power subsystems such as microcontrollers (MCUs), sensors, and infotainment components. Its low dropout voltage ensures efficient operation even when the input voltage is very close to the output level, preserving energy and reducing heat generation. Furthermore, the IC incorporates vital protection features including overcurrent protection (OCP) and thermal shutdown, safeguarding both the regulator and the downstream circuitry from potential damage.

Housed in a space-saving DFN-5 package, this LDO is designed for compact PCB layouts, which is a significant advantage in space-constrained applications. Its AEC-Q100 qualification guarantees that it meets the rigorous quality and reliability standards required for automotive electronics, ensuring long-term performance and durability.

ICGOOODFIND: The onsemi NCV8114ASN120T1G is a superior choice for designers seeking a reliable, high-voltage LDO regulator that excels in low quiescent current operation. Its combination of high input voltage tolerance, ultra-low standby power consumption, and integrated protection features makes it an ideal solution for powering always-on systems in automotive, industrial, and other demanding applications.
