NXV08V080DB1

The NXV08V080DB1 is a high-performance power management IC manufactured by onsemi, designed for efficient voltage regulation in demanding electronic systems. It operates as a low-dropout linear regulator (LDO) with a fixed output voltage of 3.3 V, capable of delivering up to 800 mA of continuous current. The device features a very low quiescent current—typically less than 50 µA—which makes it ideal for battery-powered and energy-sensitive applications such as portable electronics, IoT devices, and wearable technology. This LDO offers excellent load and line regulation, ensuring stable output voltage even under varying load conditions and input supply fluctuations. Its built-in protection mechanisms include thermal shutdown, over-current protection, and short-circuit protection, enhancing system reliability and safety. The NXV08V080DB1 also provides a high ripple rejection ratio (>60 dB at 1 kHz), minimizing noise from the input source and maintaining clean power delivery to sensitive downstream circuits like microcontrollers and analog sensors. The package type is a compact 3-pin SOT-23, which supports easy integration into space-constrained PCB designs while offering reliable thermal performance due to its optimized internal architecture. The operating input voltage range spans from 4.5 V to 5.5 V, making it compatible with standard 5 V logic supplies commonly found in industrial, automotive, and consumer electronics environments. Key features include a wide operating temperature range from -40°C to +125°C, enabling deployment in harsh environments such as automotive control units or outdoor industrial equipment. Additionally, the device is fully compliant with RoHS standards, supporting environmentally responsible manufacturing practices. Applications for the NXV08V080DB1 include power regulation in embedded systems, sensor interfaces, communication modules, and portable medical devices where stable, low-noise power is critical. Its combination of high efficiency, small form factor, and robust protection features positions it as a preferred solution for modern power management needs in both consumer and industrial markets.
