FS26

FS26 is a high-performance power management IC manufactured by NXP Semiconductors, designed for efficient voltage regulation in compact electronic systems. It operates with an input voltage range from 2.5V to 5.5V, making it suitable for a wide variety of battery-powered and low-voltage applications. The device features a low quiescent current of less than 10 µA in standby mode, which significantly enhances energy efficiency and extends battery life in portable devices. This regulator employs a fixed output voltage of 3.3V with high accuracy, typically within ±2%, ensuring stable power delivery to sensitive components such as microcontrollers, sensors, and communication modules. Its integrated over-current protection (OCP), thermal shutdown, and under-voltage lockout (UVLO) functions provide robust system reliability under varying load and environmental conditions. The FS26 also supports fast transient response, maintaining output stability during sudden load changes—a critical feature in real-time embedded systems. The device is packaged in a compact 3-pin SOT23-3 format, ideal for space-constrained designs such as wearables, IoT nodes, and smart meters. With a maximum output current capability of up to 150 mA, the FS26 balances performance and power efficiency, making it well-suited for low-power applications requiring minimal board footprint. Additionally, it includes built-in soft-start functionality to reduce inrush current during startup, minimizing stress on the power supply and improving overall system longevity. Common applications include wireless sensor networks, portable medical devices, consumer electronics, and industrial control modules where stable, efficient, and reliable power conversion is essential. The FS26’s compatibility with standard PCB assembly processes and its compliance with RoHS standards further enhance its appeal in modern, environmentally conscious manufacturing environments.
