BD15IA5MEFJ-ME2

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

The BD15IA5MEFJ-ME2 is a single-output fixed positive low-dropout linear regulator manufactured by ROHM Semiconductor. It provides a stable 1.5 V output with a maximum current capacity of 500 mA. The device operates within an input voltage range of 2.5 V to 5.5 V and maintains a typical dropout voltage of 400 mV, reaching a maximum of 600 mV. Designed for automotive applications, it holds AEC-Q100 qualification and functions reliably across a temperature range of -40°C to +105°C.

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

• AEC-Q100 qualified for automotive reliability standards
• Integrated thermal shutdown and over-current protection circuits
• High-accuracy fixed voltage regulation with minimal quiescent current consumption

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

• Automotive electronic control units requiring stable 1.5 V logic power
• Infotainment system power distribution networks
• Sensor interface circuits in vehicle body electronics

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

Verify the NRND (Not Recommended for New Designs) status before finalizing any procurement plans, as this indicates the component is no longer recommended for new designs. Confirm that existing inventory levels meet immediate production needs without relying on future supply continuity. Ensure all ordering documentation explicitly references the full ME2 suffix to guarantee correct package and tape-and-reel specifications during acquisition.

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

Select this regulator when a fixed 1.5 V rail is required for automotive-grade applications with moderate current demands up to 500 mA. It is suitable for systems where input voltages remain between 2.5 V and 5.5 V. Consider alternative parts if adjustable output or higher current capacity beyond 500 mA is necessary. Verify that the HTSOP-J8 package dimensions fit the available PCB footprint constraints.

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

This component belongs to the BD15IA5MEFJ series of high-accuracy LDO regulators designed specifically for automotive use. It shares the same pinout and general functionality with other variants in the family that offer different fixed output voltages, such as 3.3 V or 5.0 V, while maintaining identical package and thermal characteristics.

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

Direct substitutes include other ROHM automotive LDOs with matching 1.5 V output and 500 mA capability, such as the BD15IA5WEFJ-E2, provided the operating temperature range meets specific environmental requirements.
