BD80FD0WHFP-TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BD80FD0WHFP-TR is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 8 V output with a maximum continuous current of 2 A. The device operates within an input voltage range up to 35 V and features a typical dropout voltage of 400 mV at full load, with a maximum of 550 mV. It offers high ripple rejection of 50 dB and maintains a voltage regulation accuracy of ±1%. The regulator includes built-in overcurrent protection and thermal shutdown circuits for safety. It functions reliably across an extended temperature range from -40 °C to +105 °C.

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

Verify the specific suffix TR indicates tape-and-reel packaging when ordering. Confirm the HRP-5 package type matches your PCB footprint requirements. Ensure the fixed 8 V output aligns with system design needs as adjustment is not possible. Check RoHS compliance status if required by your manufacturing standards. Validate that the operating temperature range suits your environmental conditions.

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

Select this component when a fixed 8 V rail is required with up to 2 A load current. Consider the HRP-5 package for surface-mount assembly constraints. Evaluate the 50 dB ripple rejection against noise sensitivity in your circuit. Compare the 400 mV typical dropout against available headroom in your input supply. Verify thermal performance under expected ambient temperatures and load profiles.
