NCP1117LPST25T3G Description

Short technical summary and product information.

The NCP1117LPST25T3G from ON Semiconductor is a low-dropout positive linear voltage regulator designed for consumer applications. It provides a stable fixed output voltage of 2.5V and can deliver an output current exceeding 1A. The device features a low quiescent current, significantly lower than traditional 1117 regulators.

 

Key electrical characteristics include a maximum input voltage of 18V and a dropout voltage of 1.4V at 1A. Internal protection features such as output current limiting and thermal shutdown are integrated for enhanced reliability. The regulator operates within a temperature range of 0°C to 125°C.

 

This component is supplied in a SOT-223 surface-mount package, making it suitable for space-constrained designs. Its applications include TV and monitors, set-top boxes, consumer electronics, and post-regulation for switching power supplies.
