BD15FD0WHFP-TR

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

The BD15FD0WHFP-TR is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed output voltage of 1.5 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 power supply rejection ratio (PSRR) of 55 dB. It is housed in an HRP-5 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

• Fixed 1.5 V output voltage with 2 A continuous current capability
• Integrated overcurrent protection and thermal shutdown circuits
• Shutdown function for active control of the output state

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

• General-purpose linear voltage regulation
• Power management in portable electronic devices
• Biasing circuits requiring stable low-voltage supplies

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

Verify the specific suffix 'E2' or absence thereof against the manufacturer's latest datasheet, as packaging and compliance details may vary. Confirm the HRP-5 package type matches the target PCB footprint. Ensure the fixed 1.5 V output aligns with system requirements, as adjustable variants exist within the same series.

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

Select this component when a fixed 1.5 V rail is required with high current drive up to 2 A. The HRP-5 package offers a compact solution for surface-mount assembly. Consider the 55 dB PSRR for noise-sensitive applications. Verify that the input voltage remains within the 4 V to 32 V operational window to ensure proper regulation and protection circuit activation.

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

This part belongs to the BDxxFD0 series of low-saturation LDO regulators from ROHM. The series is characterized by high output current capabilities and robust protection features. It is designed for standard commercial applications rather than automotive use, as indicated by manufacturer guidelines for this product grade.

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

BA15DD0WHFP-TR is listed as a discontinued alternative; however, it has different input voltage limits (25 V max) and slightly different dropout characteristics. Verify compatibility before substitution.
