The FAN1581MX by ON Semiconductor is an adjustable ultra-low dropout linear regulator designed for high-current applications. It offers a wide input voltage range from 1.75V to 6.5V and an adjustable output voltage from 1.3V to 5.7V. With a maximum output current capability of 5A, it features a low typical dropout voltage of 0.4V at 5A, making it efficient for power-sensitive designs.
Key electrical characteristics include a typical load regulation of 0.05% and an initial accuracy of 0.5%. The device incorporates on-chip thermal limiting and current limit protection for enhanced reliability. Its high power supply rejection ratio (PSRR) of 80dB at 120Hz is beneficial for noise-sensitive applications.
The FAN1581MX is housed in a 5-lead TO-263 surface mount package, suitable for various electronic assemblies. Its operating temperature range is from 0°C to 125°C.
This regulator is well-suited for applications such as GTL+ bus supply, low voltage logic supplies, embedded processor supplies, and DDR termination supplies, where stable and regulated power is critical.
