NCP1117ST25T3G Description

Short technical summary and product information.

The NCP1117ST25T3G is a positive fixed output linear voltage regulator manufactured by On Semiconductor. It provides a regulated 2.5V output with a nominal output current capability of 1A. The device features a maximum dropout voltage of 1.2V at 800mA load, making it suitable for low dropout applications.

 

Key electrical specifications include an input voltage rating of 20V, a power supply rejection ratio (PSRR) of 68dB at 120Hz, and built-in protection features including over current and over temperature protection. The operating temperature range is 0°C to 125°C.

 

The regulator is available in a surface mount SOT-223 package (also referenced as TO-261-4, TO-261AA). This package is suitable for automated assembly and space-constrained designs. The device is RoHS3 compliant (unverified) and has an MSL of 1 (unlimited floor life).
