BD00FD0WHFP-TR

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

The BD00FD0WHFP-TR is a high-side linear voltage regulator from ROHM Semiconductor, part of the BDxxFD0 series. It provides a positive adjustable output voltage ranging from 1.5 V to 16 V with a maximum output current of 2 A. The device operates within an input voltage range of 4 V to 32 V and features a typical dropout voltage of 0.4 V at 1 A load. It includes shutdown functionality, thermal shutdown protection, and overcurrent protection. The regulator offers a ripple rejection of 55 dB and maintains a line regulation of 20 mV. It is housed in an HRP-5 surface-mount package and operates between -40°C and +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 dimensions match your PCB footprint requirements. Ensure input voltage does not exceed 32 V to prevent damage. Check that the required output voltage falls within the 1.5 V to 16 V adjustable range. Validate thermal management strategies for operation up to 105°C ambient temperature.

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

Select this component when a high-side LDO with 2 A capability is required. Choose the adjustable version if flexible output voltage settings are needed. Consider the HRP-5 package for space-constrained surface-mount designs. Verify compatibility with downstream loads requiring positive voltage regulation. Evaluate thermal dissipation needs based on expected load currents and ambient conditions.

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

This part belongs to the BDxxFD0 series of single-output LDO regulators from ROHM. The series includes fixed and adjustable variants with 2 A output current and 35 V withstand voltage. These regulators are designed for standard-grade applications and are not recommended for automotive equipment. The series emphasizes low saturation characteristics and integrated protection features.

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

Check ROHM datasheets for other BDxxFD0 variants with compatible pinouts. Verify equivalent current and voltage ratings before substitution. Ensure package type matches for physical replacement. Confirm functional similarities in protection features and shutdown capabilities.
