NCP161BFCT250T2G Description

Short technical summary and product information.

The NCP161BFCT250T2G is a linear voltage regulator from On Semiconductor designed to provide a fixed 2.5V output with up to 450mA of load current. It operates from an input voltage range of 1.9V to 5.5V, making it suitable for a variety of battery-powered and low-voltage applications. The device features a very low dropout voltage of typically 150mV at 450mA, allowing efficient operation even when the input supply is close to the output voltage.

 

The regulator offers excellent noise performance with an ultra-low output noise of 10µVRMS and a high PSRR of 98dB at 1kHz, making it ideal for noise-sensitive analog and RF circuits. Quiescent current is typically 18µA, which helps extend battery life in portable devices. The output voltage accuracy is ±2% over load and temperature, ensuring reliable regulation.

 

The device is available in a compact 4-WLCSP package, suited for space-constrained designs such as wearables, sensor modules, and wireless devices. It operates over a junction temperature range of -40°C to 125°C, supporting demanding environments.
