BD25HC5JEFJ-E2

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

The BD25HC5JEFJ-E2 is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a stable 2.5V output with a maximum continuous current of 1.5A. The device operates within an input voltage range of 4.5V to 8V and features a typical dropout voltage of 600mV at full load. It utilizes HTSOP-J8 surface-mount packaging and includes integrated protection circuits for overcurrent, thermal shutdown, and soft start functionality.

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

• Integrated overcurrent protection circuit prevents IC damage during output short circuits.
• Built-in shutdown function reduces standby current to 0µA when disabled.
• Thermal shutdown circuit protects the device from overheating under overload conditions.
• Soft start feature minimizes inrush current during power-up sequences.

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

Verify the specific suffix JEFJ against the official ROHM datasheet to confirm pinout and electrical characteristics. Ensure the HTSOP-J8 package footprint matches the design layout. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement specifications.

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

Select this component for applications requiring a fixed 2.5V output up to 1.5A with an input supply between 4.5V and 8V. Consider the 600mV typical dropout voltage for efficiency calculations. Verify that the operating temperature range of -25°C to +85°C meets the environmental requirements of the target system.

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

This LDO regulator belongs to the BD25HC series designed for digital appliance applications. It is produced on a dedicated manufacturing line distinct from the BD25HCW series to improve production efficiency, though electrical characteristics remain consistent. The device is intended for general industrial use and is not recommended for automotive equipment.

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

The BD25HC5WEFJ-E2 is a related model using a different production line but sharing identical electrical characteristics. Designers may consider it as a functional substitute if available, provided the package compatibility is verified.
