FAN1112SX Description

Short technical summary and product information.

The FAN1112SX from ON Semiconductor is a three-terminal, fixed 1.2V low dropout linear regulator designed for high-performance applications. It offers a 1A output current capability and is optimized for low voltage requirements where transient response and minimum input voltage are critical.

 

Key features include a low dropout voltage, typical load regulation of 0.05%, trimmed current limit, and on-chip thermal limiting for protection. The device operates over a junction temperature range of 0°C to 125°C and has an input voltage rating up to 18V.

 

This regulator is available in industry-standard SOT-223 and TO-252 (DPAK) packages, suitable for surface mount applications. Its design ensures that quiescent current flows into the load, enhancing efficiency compared to PNP type regulators. It is well-suited for use as a post regulator for switching supplies or as a supply for low-voltage processors.
