Overview
The NCP176BMX180TCG is a high-performance, low dropout linear regulator (LDO) from onsemi, designed to deliver excellent noise and dynamic performance. This CMOS LDO regulator features a 500 mA output current and is suitable for a wide range of applications, particularly in portable and noise-sensitive devices. The regulator operates with an input voltage range of 1.4 V to 5.5 V and can set the output voltage from 0.7 V to 3.6 V in 0.1 V steps. The NCP176BMX180TCG is specifically configured for an output voltage of 1.8 V and does not include the output discharge function.
