Overview
The NCP176AMX300TCG is a high-performance, low dropout linear regulator (LDO) from onsemi, designed to deliver excellent noise and dynamic performance. This CMOS LDO regulator features an output current of 500 mA and is suitable for a wide range of applications, particularly in portable and noise-sensitive devices. The regulator operates with an input voltage as low as 1.4 V and can set the output voltage from 0.7 V in 0.1 V steps. It is available in a compact XDFN6 package, measuring 1.2 mm x 1.2 mm x 0.4 mm, and is Pb-free, making it an environmentally friendly option.
