BDJ2GA5MEFJ-ME2

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

The BDJ2GA5MEFJ-ME2 is a fixed-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor. It provides a stable 2.5 V output with a maximum continuous current of 500 mA. The device operates within an input voltage range of 4.5 V to 14 V and features a typical dropout voltage of 600 mV at full load. Packaged in an HTSOP-J8 surface-mount format, it supports operation from -40°C to +105°C. Key electrical specifications include a line regulation of 25 mV, load regulation of 25 mV, and a quiescent current of approximately 900 µA.

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

• Integrated overcurrent protection and thermal shutdown circuits to prevent damage during fault conditions.
• Includes a shutdown function that reduces circuit current to zero when activated.
• Features soft-start capability to limit inrush current during power-up.

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

Verify the specific suffix ME2 against official ROHM documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before procurement. Ensure the component meets automotive qualification requirements if intended for such environments, as standard versions may differ from AEC-Q100 certified variants.

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

Select this component for applications requiring a fixed 2.5 V rail with moderate current demands up to 500 mA. The HTSOP-J8 package offers thermal efficiency suitable for compact designs. Consider the 600 mV dropout voltage when designing for low input-to-output differential scenarios. Verify that the required operating temperature range aligns with the specified -40°C to +105°C limits.

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

This part belongs to the BDJ2GA5WEFJ series of LDO regulators designed for general-purpose use. While sharing similar pinouts and basic functionality with other members of the family, the BDJ2GA5MEFJ-ME2 specifically denotes the 2.5 V fixed output variant. It is distinct from automotive-grade counterparts which may carry different qualification markings or extended reliability standards.
