BD25HA5WEFJ-E2

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

The BD25HA5WEFJ-E2 is a positive fixed-output Low Dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 2.5 V output with a maximum current capacity of 0.5 A. The device operates within an input voltage range of 4.5 V to 8 V and features a typical dropout voltage of 600 mV, reaching a maximum of 900 mV. It 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 Feature Summary

• Integrated overcurrent protection circuit to prevent IC damage during output short circuits.
• Built-in shutdown function that reduces circuit current to zero when disabled.
• Thermal protection circuit prevents thermal destruction under overload conditions.

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

• Digital home appliances
• General-purpose power management systems

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

Verify the specific suffix E2 against official ROHM documentation to confirm pinout and electrical characteristics match design requirements. Confirm HTSOP-J8 package dimensions for PCB layout compatibility. Ensure input voltage stays within the 4.5 V to 8 V limit to maintain regulation. Check ambient temperature constraints against the -25°C to +85°C operating range.

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

Select this component when a fixed 2.5 V rail is required from a 4.5 V to 8 V source. The HTSOP-J8 package suits space-constrained surface-mount designs. Consider the 600 mV typical dropout for efficiency relative to input voltage. Verify that the 0.5 A load current does not exceed thermal dissipation limits in the target enclosure.

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

This part belongs to the BDxxHA5WEFJ series of automotive-grade LDO regulators. It shares the HTSOP-J8 package and core protection features with other variants in the family, differing primarily in fixed output voltage settings such as 1.5 V, 6.0 V, or 7.0 V.

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

Direct substitutes include BD15HA5WEFJ-E2 (1.5 V), BD60HA5WEFJ-E2 (6.0 V), and BD70HA5WEFJ-E2 (7.0 V). These share identical packages and protection features but provide different fixed output voltages.
