BD950M5WFP-CE2

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

The BD950M5WFP-CE2 is a fixed-output low-dropout (LDO) linear voltage regulator manufactured by ROHM Semiconductor. It provides a stable 5 V output with a maximum load current of 500 mA. The device supports an input voltage range from 3 V to 42 V and features a typical ripple rejection ratio of 70 dB. It operates within an ambient temperature range of -40°C to +125°C and utilizes a TO-252-5 surface-mount package. Key electrical parameters include a line regulation of 0.1%, a load regulation of 0.1%, and a quiescent current of 8 µA.

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

Verify the specific suffix CE2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the TO-252-5 package footprint matches the design layout. Confirm that the 5 V fixed output aligns with the target circuit requirements before procurement.

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

Select this component when a fixed 5 V rail is required with moderate current capacity up to 500 mA. It is suitable for applications needing an enable/shutdown control feature via the output shutdown pin. Consider the 42 V maximum input rating for systems connected directly to vehicle batteries or noisy power lines.

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