NCP139AFCT180T2G Description

Short technical summary and product information.

The NCP139AFCT180T2G from ON Semiconductor is a linear voltage regulator capable of delivering up to 1A of current. It operates with an input voltage range up to 5.5V and provides a fixed 1.8V output. This device includes Under Voltage Lockout (UVLO) protection to ensure reliable operation.

 

The regulator is designed for surface mount applications and comes in a compact 6-WLCSP package measuring 1.2x0.8mm. Its operating temperature range is -40°C to 85°C (TA), making it suitable for various environmental conditions. The PSRR is rated between 85dB and 70dB at 1kHz, indicating good power supply ripple rejection.

 

This component is part of the NCP139 series, which focuses on LDO regulators. Its fixed output and current handling capabilities make it suitable for applications requiring stable voltage regulation. The enable control feature allows for power sequencing and management.

 

Key electrical characteristics include a typical voltage dropout of 1.5V at 1A. The device is designed for single regulator applications. Its small package size and surface mount capability facilitate integration into compact electronic designs.
