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

Verify the specific suffix and tape-and-reel quantity requirements against the official datasheet before ordering. Confirm that the HRP-5 package dimensions match your PCB footprint design. Ensure compliance with RoHS directives if required by your manufacturing standards. Check for any recent product change notifications or end-of-life announcements directly from the manufacturer's official channels.

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

Select this component when a fixed 5V output with 2A capability is required in a compact surface-mount format. Consider the 0.45V dropout voltage for efficiency calculations under full load conditions. Evaluate the 55dB ripple rejection for noise-sensitive analog sections. Compare the HRP-5 thermal performance against alternative packages like TO-220FP if heat dissipation is a primary constraint in the enclosure design.

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

This part belongs to the BAxxDD0 series of 2A fixed output LDO regulators from Rohm Semiconductor. The series offers various output voltages and includes variants with and without shutdown switches. The WHFP suffix indicates the HRP-5 surface-mount package type. This family is engineered for low saturation characteristics, making it suitable for applications where input-output voltage differentials are minimal.

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

BA50DD0WT is a pin-compatible through-hole alternative in the TO-220FP-5 package offering identical electrical specifications. BD50FD0WHFP-TR is a recommended manufacturer substitute in the same HRP-5 package but may differ in input voltage ratings or internal topology; verify datasheet compatibility before substitution.
