BD950M5FP-CE2

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

The BD950M5FP-CE2 is a fixed-output Low Dropout (LDO) regulator from ROHM Semiconductor's QuiCur automotive series. It provides a stable 5 V output with a maximum load current of 500 mA in a TO-252-3 surface-mount package. The device features a typical dropout voltage of 740 mV and a ripple rejection ratio of 70 dB. It operates within an input voltage range of 3 V to 42 V, with a maximum absolute rating of 45 V. Quiescent current is typically 8 µA. The unit supports an extended operating temperature range from -40°C to +125°C and includes line regulation and load regulation of 0.1%.

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

Verify the specific suffix CE2 against official ROHM documentation to confirm compliance with automotive quality standards and RoHS directives. Ensure the TO-252-3 package variant matches your PCB footprint requirements. Confirm that the fixed 5.0 V output aligns with your system design before procurement, as this parameter cannot be adjusted externally.

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

Select this component when a robust automotive-grade LDO with high input voltage tolerance up to 42 V is required. The TO-252-3 package offers suitable thermal dissipation for 500 mA loads. Consider the 70 dB ripple rejection for noise-sensitive applications. Verify that the 5 V fixed output meets your target rail requirements without needing external feedback networks.

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

This part belongs to the BD950M5-C series of linear regulators designed for automotive use. The series utilizes QuiCur technology to balance low current consumption with high-speed transient response. These devices are engineered to support functional safety analysis, making them suitable for critical vehicle electronics where reliability and precise voltage regulation are paramount.

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

Check for other suffixes in the BD950M5 family, such as EFJ or WEJ, which may offer different pinouts or enable functions. Ensure any substitute maintains the same 5 V output, 500 mA current rating, and automotive qualification level. Verify package compatibility if replacing with a different form factor.
