The NCP187AMT330TAG is a low dropout (LDO) voltage regulator IC manufactured by ON Semiconductor. It boasts a 1.2A output, with a 3.3V active discharge voltage rating. This regulator has a drop-out voltage (Vdrop) of only 200mV, which means it can provide precision voltage control with minimal power dissipation. It also has a wide temperature range, from -40°C to +85°C, making it suitable for many applications. It has built-in overcurrent protection, and it can be used with ceramic capacitors for increased power stability and reduced costs. The NCP187AMT330TAG is ideal for applications requiring very low noise and high accuracy, such as mobile phones, portable electronic devices, and personal computers.
