NCP137BFCTADJT2G is listed in the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators range at ChipApex. The manufacturer field lists onsemi. Its product description is IC REG LIN POS ADJ 700MA 6-WLCSP. Review the specifications below when checking this part for your BOM.
The NCP137BFCTADJT2G is a positive adjustable linear regulator from onsemi, delivering up to 700mA output current. It features an input voltage range of 1.1V to 5.5V and an adjustable output voltage range from 0.5V to 3V. The device offers a maximum dropout voltage of 1.5V at full load and includes power supply rejection ratios (PSRR) ranging from 85dB to 75dB at 1kHz. It incorporates enable control and under-voltage lockout (UVLO) protection, operating within a temperature range of -40°C to +85°C in a compact 6-WLCSP package.
Verify the specific suffix 'ADJT' confirms the adjustable output variant rather than fixed voltage options. Confirm the 'C' indicates the WLCSP package type and 'T2G' denotes tape-and-reel packaging with lead-free compliance. Cross-reference the manufacturer part number against official datasheets to ensure correct pinout and thermal specifications for your PCB layout.
Select this component when a compact solution is required for low-current applications needing adjustable voltage levels. Ensure the input voltage remains within the specified 5.5V maximum limit. Consider the thermal performance of the WLCSP package if operating near the upper limits of the current or temperature specifications.
This part belongs to the NCP137 family of 700mA LDO regulators designed for ultra-low dropout performance. The series supports both fixed and adjustable output configurations, catering to diverse power management needs in space-constrained mobile and industrial devices. The NCP137 line emphasizes efficiency and noise reduction for sensitive analog loads.
