FAN1117AS25X Description

Short technical summary and product information.

The FAN1117AS25X from ON Semiconductor is a low dropout linear voltage regulator. It provides a fixed 2.5V output voltage and can deliver up to 1A of current. This device features a low dropout voltage of 1.2V at 1A, making it suitable for applications where input voltage is close to the output voltage.

 

Designed for efficiency, the FAN1117AS25X operates with a low quiescent current that flows into the load. It includes built-in protection features such as over-current and over-temperature limiting. The regulator is available in a surface-mount SOT-223-4 package, suitable for compact designs.

 

Key electrical characteristics include an operating temperature range of 0°C to 125°C and a PSRR of 72dB at 120Hz. The device is designed for positive voltage regulation.

 

Applications include active SCSI terminators, high efficiency linear regulators, post regulators for switching supplies, battery chargers, and 12V to 5V linear regulators.
