BD950N5FP-CE2

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

The BD950N5FP-CE2 is a fixed-output low-dropout (LDO) voltage regulator manufactured by ROHM Semiconductor. It provides a stable 5 V output with a maximum continuous current of 500 mA. The device operates within an input voltage range of 3 V to 42 V and features a typical dropout voltage of 700 mV. It includes internal protection mechanisms against overcurrent, thermal overload, and reverse polarity. The regulator is designed for surface-mount installation in the TO-263-3 package.

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

Verify the specific suffix CE2 matches the required RoHS compliance and tape-and-reel packaging configuration. Confirm that the TO-263-3 footprint aligns with the target PCB layout. Ensure the 5 V fixed output variant meets the circuit design requirements before finalizing procurement orders.

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

Select this component when a 5 V rail is required from a higher automotive bus voltage up to 42 V. The 500 mA capacity suits moderate load applications. The Nano Cap feature reduces external capacitor count, saving board space. Verify thermal dissipation capabilities in the TO-263-3 package under expected operating conditions.

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

This part belongs to the BD9xxN5-C series of automotive-grade LDO regulators. The series utilizes proprietary Nano Cap and QuiCur technologies to enhance performance in noisy automotive environments. It is designed to replace older linear regulator designs requiring larger external components for stability.

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

Direct substitutes include other BD950 variants with different packages such as BD950M5FP-CE2 or BD950N5EFJ-CE2. Ensure the replacement maintains the 5 V output and 500 mA current rating while matching the physical footprint if board space is constrained.
