The NCP139AFCT05ADJT2G is a linear voltage regulator designed for low dropout applications, featuring a maximum output current of 1 A and a very low dropout voltage of approximately 50 mV at 1 A. It operates with an input voltage range from the output voltage up to 5.5 V and requires a bias voltage between 3.0 V and 5.5 V. The output voltage can be adjusted from 0.5 V to 3.0 V for adjustable versions, while fixed versions are available with output voltages from 0.4 V to 1.8 V. This device is optimized for battery-powered and space-constrained applications, with a very low quiescent current of 35 µA and a minimal current draw of 0.5 µA in disable mode. It includes features such as a logic level enable input for ON/OFF control and an optional output active discharge function. The NCP139AFCT05ADJT2G is packaged in a compact WLCSP6 format measuring 1.2 mm x 0.8 mm, making it suitable for integration into small electronic devices. The product is also compliant with RoHS standards, being Pb-free and halogen-free.
