Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific manufacturer part number against official ROHM documentation to ensure compatibility. Confirm that the DFN-4 package footprint matches your PCB design requirements. Check the latest datasheet for any updates regarding thermal performance or electrical characteristics before finalizing component selection.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.75 V output is required with moderate current demands. Ensure the input voltage exceeds the minimum dropout requirement for the expected load current. Consider the thermal dissipation capabilities of the DFN-4 package relative to the ambient operating conditions and power loss calculations.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This part belongs to the BU2HUA3WNVX series of low-dropout regulators from ROHM Semiconductor. It shares the same DFN-4 package form factor as other variants in the family, such as the BU19UA3WNVX and BU30UA3WNVX, differing primarily in the fixed output voltage setting while maintaining similar current handling capabilities.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Direct substitutes within the same series include BU19UA3WNVX (1.9V) and BU30UA3WNVX (3.0V), provided the system voltage tolerance allows for the difference. Verify pinout compatibility and thermal characteristics when swapping between these fixed-voltage variants.
