BD25IA5WEFJ-E2

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

The BD25IA5WEFJ-E2 is a high-accuracy low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed positive output voltage of 2.5 V with a maximum output current of 500 mA. The device operates within an input voltage range of 2.4 V to 5.5 V and maintains a load regulation of 1.5%. Quiescent current is specified at 250 uA. It is housed in an HTSOP-J8 surface-mount package and functions reliably across a temperature range of -25°C to +85°C.

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

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm humidity sensitivity handling requirements during storage and assembly. Ensure the HTSOP-J8 footprint matches the design layout. Cross-reference the part number alias BD25IA5WEFJ if sourcing from legacy inventories.

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

Select this component when a fixed 2.5 V rail is required with moderate current capability up to 500 mA. The 250 uA quiescent current makes it less ideal for ultra-low-power standby modes compared to variants with lower static current. Verify that the input voltage remains above the minimum threshold of 2.4 V under all operating conditions.

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

This part belongs to the BDxxIA5WEFJ series of LDO regulators from ROHM Semiconductor. The series includes various fixed and adjustable output voltage options sharing similar packaging and protection features. The BD25 variant specifically targets applications needing a precise 2.5 V reference or supply voltage within the standard 3.3 V or 5 V system architectures.

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

BD25KA5WF-E2 offers similar electrical performance but utilizes an SOP-8 package instead of HTSOP-J8. BD33IA5WEFJ-E2 provides a 3.3 V output with identical package and current ratings. BD12IA5WEFJ-E2 and BD15IA5WEFJ-E2 provide lower fixed voltages of 1.2 V and 1.5 V respectively using the same HTSOP-J8 form factor.
