BA00DD0WHFP-TR

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

The BA00DD0WHFP-TR is a positive adjustable linear voltage regulator from ROHM Semiconductor, housed in an HRP-5 surface-mount package. It delivers a maximum output current of 2A with a typical dropout voltage of 0.45V at full load. The device features a wide input voltage range up to 35V and offers high voltage regulation accuracy of ±1.0% at 25°C. It includes built-in protection circuits for over-current, thermal shutdown, and over-voltage conditions, operating reliably within a temperature range of -40°C to 125°C.

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

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

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

Select this component when a fixed-output LDO is insufficient and adjustable voltage is required. The 2A current capability suits moderate-power applications where low noise and simple external resistor setting are preferred. Consider the thermal performance in your enclosure design due to the linear regulation topology. Verify that the input voltage does not exceed the 35V maximum rating during all operating conditions.

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

This part belongs to the BA00 series of low-dropout regulators designed for robust performance in automotive and industrial environments. The HRP-5 package provides a compact solution for surface-mount assembly while maintaining adequate thermal dissipation characteristics for 2A operation. It complements other variants in the family that offer fixed outputs or different packaging options.

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

Direct substitutes include BA00DD0WHFP (non-tray version) or BA00DD0WCP-V5E2 for through-hole applications. Cross-reference with BA00DD0T for TO-220FP-3 mounting needs. Always verify pinout compatibility and thermal resistance values before substituting.
