BD25IA5MEFJ-ME2

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

The BD25IA5MEFJ-ME2 is a high-accuracy linear low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a fixed positive output of 2.5 V with a maximum load current capability of 500 mA. The device operates within an input voltage range of 2.4 V to 5.5 V and maintains a typical dropout voltage of 400 mV at full load, with a maximum of 600 mV. Quiescent current is specified at 250 uA. It features line regulation of 1% and load regulation of 1.5%. The component is housed in an HTSOP-J8 surface-mount package and is designed for 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 suffixes to ensure correct packaging and tape-and-reel specifications. Confirm that the required output voltage and current ratings align with system design constraints. Check for RoHS compliance documentation if environmental regulations apply. Ensure the HTSOP-J8 footprint matches the PCB layout requirements. Validate thermal dissipation capabilities based on expected ambient temperatures and load currents.

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

Select this regulator when a fixed 2.5 V output is required with moderate current demands up to 500 mA. Consider the 2.4 V minimum input voltage for battery-operated applications where headroom is limited. Evaluate the 250 uA quiescent current against system standby power budgets. Compare the HTSOP-J8 package size against available board space. Assess thermal performance given the 2.11 W power dissipation rating under worst-case conditions.

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

This component belongs to ROHM's LDO voltage regulator family, specifically designed for power management integrated circuits. It shares the HTSOP-J8 package form factor with other variants in the series, such as the BD25HA5MEFJ-ME2 and BD33IA5VEFJ-ME2. These parts typically offer similar current capabilities but differ in output voltage, input voltage ranges, and automotive qualification levels.

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

The BD25HA5MEFJ-ME2 offers a similar 2.5 V output and 500 mA current capacity but features an extended operating temperature range from -40°C to +105°C and AEC-Q100 automotive qualification. Verify input voltage compatibility, as the HA variant specifies a 4.5 V minimum input compared to the 2.4 V minimum of the IA variant.
