NCP139AFCTC110T2G Description

Short technical summary and product information.

The NCP139AFCTC110T2G from ON Semiconductor is a 1A Very Low Dropout (VLDO) linear voltage regulator. It features a fixed output voltage of 1.1V and is designed for space-constrained, noise-sensitive applications.

 

This regulator provides stable and accurate output voltage with an ultra-low dropout of typically 50 mV at 1A. It operates with an input voltage range up to 5.5V and features low quiescent current consumption, making it suitable for battery-operated equipment.

 

The device is available in a compact 6-WLCSP (1.2 mm x 0.8 mm) package, ideal for portable applications like smartphones and tablets. It includes an enable pin for ON/OFF control and protection features such as Under Voltage Lockout (UVLO).

 

Key electrical specifications include a PSRR of up to 75 dB, ±1% accuracy over temperature, and a line regulation of 0.01%/V. The operating temperature range is -40°C to 85°C.
