NCV8165

The NCV8165 is a high-efficiency, low-dropout linear regulator (LDO) manufactured by onsemi, designed for automotive and industrial applications requiring stable power delivery under varying conditions. It features a maximum output current of 1.5 A, making it suitable for powering microcontrollers, sensors, and other low-power peripherals in demanding environments. The device operates with an input voltage range from 4.5 V to 28 V, allowing compatibility with a wide range of power sources including automotive battery systems. This LDO incorporates advanced thermal protection and over-current protection mechanisms to ensure reliable operation even under fault conditions. Its low quiescent current—typically 3.5 mA at full load—enhances system efficiency, particularly in always-on or sleep-mode scenarios common in modern vehicle electronics. The NCV8165 also offers excellent line and load regulation, maintaining a stable output voltage within ±1% across temperature and load variations, which is critical for sensitive analog and digital circuits. Designed for robust performance in harsh environments, the NCV8165 meets AEC-Q100 Grade 1 qualification standards, ensuring reliability in automotive-grade applications such as infotainment systems, ADAS (Advanced Driver Assistance Systems), body control modules, and engine control units. It supports both surface-mount and through-hole mounting options, providing flexibility in PCB layout design. Key features include a programmable soft-start function that minimizes inrush current during startup, reducing stress on the power supply and connected components. Additionally, the device includes an active-low enable pin for remote control of power-up and shutdown sequences, enabling integration into complex power management architectures. The internal protection circuitry includes reverse battery protection, thermal shutdown, and current limiting, further enhancing safety and longevity in real-world usage. With its compact footprint and efficient thermal performance, the NCV8165 is ideal for space-constrained designs where reliability, precision, and ease of integration are paramount. Its wide operating temperature range—from -40°C to +125°C—makes it well-suited for extreme environmental conditions typical in automotive and industrial settings.
