NCP1117LPST33T3G Description

Short technical summary and product information.

The NCP1117LPST33T3G from ON Semiconductor is a low-power version of the NCP1117 family, designed for high-volume consumer applications. This linear voltage regulator offers a fixed output voltage of 3.3V and can supply an output current in excess of 1A. It features a low dropout voltage of 1.4V at 1A, making it efficient for power management.

 

Key electrical characteristics include a maximum input voltage of 18V, a typical quiescent current significantly lower than traditional 1117 regulators, and good noise rejection. Internal protection features such as output current limiting and thermal shutdown are integrated for reliability. The device operates within a temperature range of 0°C to 125°C.

 

Packaged in a SOT-223 surface-mount package, the NCP1117LPST33T3G is suitable for space-constrained designs. Its fixed output voltage and no minimum load requirement for fixed voltage outputs simplify circuit design. Applications include TV and monitors, set-top boxes, game consoles, and consumer electronics.
