NCP163BFCT2925T2G

Product Overview

The NCP163BFCT2925T2G from onsemi is a surface-mount linear voltage regulator that provides a single positive fixed 2.925 V output at up to 250 mA. It operates from a maximum input voltage of 5.5 V and includes an enable control for managed power-up or power-down. The device is supplied in a 4-WLCSP (0.64x0.64) package, with a 4-XFBGA, WLCSP case designation, and is rated for an ambient temperature range of -40°C ~ 125°C (TA).

Key Features

• Single positive fixed output delivering 2.925 V at up to 250 mA.
• Maximum input voltage of 5.5 V.
• Enable control for regulator on/off management.
• Protection features include over current, over temperature, and soft start.
• Quiescent current of 20 µA and PSRR of 91 dB ~ 60 dB (100 Hz ~ 100 kHz).
• Surface-mount 4-WLCSP (0.64x0.64) package, identified as 4-XFBGA, WLCSP.
• Operating temperature range of -40°C ~ 125°C (TA).

Applications

• Battery-powered portable devices needing a fixed 2.925 V rail for 250 mA class loads.
• Embedded sensor or processing modules where the 4-WLCSP footprint and enable control support space-constrained power sequencing.
• Control boards requiring a fixed positive 2.925 V supply with over current, over temperature, and soft start protection.

Design & Procurement Notes

Designers should confirm that the input supply does not exceed 5.5 V and that the load remains within the 250 mA output current limit. The fixed 2.925 V output does not provide adjustable voltage selection, so the rail voltage must match the target subsystem. The 20 µA quiescent current and enable control support power-managed circuits, while the PSRR of 91 dB ~ 60 dB (100 Hz ~ 100 kHz) should be considered when filtering sensitive analog or digital supplies. The -40°C ~ 125°C (TA) operating range, over current, over temperature, and soft start protections, and the 4-WLCSP (0.64x0.64) package should be reviewed during PCB layout, thermal planning, and assembly preparation.
