BD25HC5WEFJ-E2

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

The BD25HC5WEFJ-E2 is a high-accuracy fixed-voltage Low Dropout (LDO) regulator manufactured by ROHM Semiconductor. It provides a stable 2.5 V output with a maximum continuous current of 1.5 A. The device operates within an input voltage range of 4.5 V to 8 V and maintains a load regulation of 1.5%. It features a typical dropout voltage of 0.6 V at full load and consumes 600 uA of quiescent current. The component is housed in an HTSOP-J8 surface-mount package and supports operation across a temperature range of -25°C to +85°C.

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

Verify the complete part number including the suffix to ensure correct configuration. Confirm that the required output current does not exceed the 1.5 A limit under your specific thermal conditions. Check datasheet specifications for derating curves if operating near the maximum temperature range. Ensure input voltage remains within the 4.5 V to 8 V window to prevent malfunction or damage.

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

Select this component when a fixed 2.5 V rail is required with up to 1.5 A capacity. It is suitable for designs prioritizing accuracy and built-in protection features over adjustable output flexibility. Consider the HTSOP-J8 package constraints for thermal dissipation. Verify that the system input voltage aligns with the specified 4.5 V minimum requirement.

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

This regulator belongs to the BD25HC series of high-accuracy LDO regulators from ROHM. The series is characterized by its ability to drive significant currents while maintaining tight voltage tolerances. The BD25HC5WEFJ-E2 variant specifically targets applications needing a fixed 2.5 V supply, distinguishing it from adjustable or different voltage variants within the same family.

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

Direct substitutes include other ROHM BD25HC series parts with identical pinouts and electrical characteristics but different output voltages or current ratings, provided the system design accommodates those differences. Cross-manufacturer replacements require careful verification of pin compatibility, thermal performance, and regulatory compliance.
