onsemi Voltage Regulators - Linear FAN1086D5X

The FAN1086D5X is a low dropout linear voltage regulator capable of delivering up to 1.5A of output current. It features a fixed output voltage of 5V and is designed for applications requiring efficient voltage regulation with minimal input-output voltage differential. The device exhibits a typical load regulation of 0.05% and a dropout voltage of 1.5V at maximum load, ensuring stable performance under varying load conditions. This regulator includes on-chip thermal limiting for protection against overheating and has a trimmed current limit to maintain specified output current levels. The quiescent current is designed to flow into the load, enhancing overall efficiency compared to traditional PNP regulators. The FAN1086D5X is available in a TO-252 package, which is a standard choice for power applications, facilitating easy integration into various circuit designs. Engineers may consider this product for applications such as battery chargers, motherboard clock supplies, and post regulators for switching supplies, where low dropout and high efficiency are critical.
