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

Verify the exact suffix TR indicates reel packaging when ordering. Confirm the HRP-5 package type matches your PCB footprint requirements. Ensure input voltage does not exceed the 35V absolute maximum rating. Check for RoHS compliance documentation if required by your manufacturing standards. Validate that the fixed 9V output meets your circuit design specifications before procurement.

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

Select this component when a fixed 9V output is required with up to 2A current capacity. It is suitable for applications needing low dropout performance under varying load conditions. Consider the HRP-5 package size for space-constrained designs. Ensure the operating temperature range of -40°C to +105°C aligns with your environmental requirements. Verify that the 55dB ripple rejection is sufficient for your noise-sensitive applications.

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

This part belongs to the BDxxFD0 series of LDO regulators from ROHM. The series offers various fixed output voltages, including 3.3V, 5.0V, and 9.0V options. All variants share similar electrical characteristics, such as 2A output current and 35V withstand voltage. The BD90FD0WHFP-TR specifically provides the 9V variant in the same family.

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

Compatible substitutes include other parts from the BDxxFD0 series with different fixed output voltages, such as BD33FD0WHFP-TR or BD50FD0WHFP-TR, provided the voltage requirement differs. Ensure any replacement maintains the same HRP-5 package and 2A current rating.
