BD950M5EFJ-CE2

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

The BD950M5EFJ-CE2 is a fixed-output low-dropout (LDO) linear regulator from ROHM Semiconductor, designed for automotive applications. It provides a stable 5.0 V output with a maximum load current of 500 mA. The device supports an input voltage range from 3 V to 42 V and operates within a temperature range of -40°C to +150°C. Key electrical parameters include a typical ripple rejection ratio of 70 dB, a quiescent current of 9.5 µA, and an input bias current of 8 µA. Line and load regulation are both specified at 0.1%. The dropout voltage is typically 680 mV, with a maximum of 1.3 V. It is housed in an HTSOP-J8 surface-mount package.

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

Verify the specific suffix CE2 against the official ROHM datasheet to confirm pin configuration and packaging details. Ensure compatibility with automotive functional safety standards if required by the system design. Confirm that the HTSOP-J8 package footprint matches the PCB layout specifications. Check for RoHS compliance documentation as indicated in the product attributes.

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

Select this component when a fixed 5.0 V output is required with high current capability up to 500 mA. It is suitable for designs needing low quiescent current to minimize standby power consumption. The wide input voltage range allows flexibility in upstream power stages. Consider the thermal performance in the HTSOP-J8 package under maximum load conditions.

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

This part belongs to the BD950M5-C series of automotive LDO regulators. The series utilizes QuiCur technology for enhanced transient response. Other variants in the family offer different output voltages or packages, such as the BD950M5WFP-CE2 in a TO-252-5 package. The BD950M5EFJ-CE2 specifically targets applications requiring the compact HTSOP-J8 form factor.

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

Direct substitutes may include other BD950M5 series parts with identical electrical specifications but different packages, such as BD950M5WFP-CE2. Verify pin-to-pin compatibility and thermal dissipation capabilities before substitution. Alternative LDOs must match the 500 mA output current and 42 V input voltage limits.
