BD950N5WEFJ-CE2

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

The BD950N5WEFJ-CE2 is a fixed-output low-dropout (LDO) regulator from ROHM Semiconductor, designed for automotive applications. It provides a stable 5 V output with a maximum current of 500 mA. The device operates within an input voltage range of 3 V to 42 V and features a typical power supply rejection ratio (PSRR) of 60 dB. It utilizes the Nano Cap™ technology for stability with small output capacitors and QuiCur™ technology for fast load response. The regulator includes an enable input, thermal shutdown, and overcurrent protection. It is qualified under AEC-Q100 standards and housed in an HTSOP-J8 package.

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

Verify the specific suffix CE2 against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with AEC-Q100 automotive qualification requirements for your target application environment. Check for functional safety support status if required by system design. Confirm RoHS compliance details through official documentation before procurement.

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

Select this component when a fixed 5 V output is required with up to 500 mA load capability in automotive environments. Consider its low quiescent current and wide input voltage range suitable for direct battery interfacing. Evaluate the need for Nano Cap™ stability benefits if using minimal external capacitance. Verify that the HTSOP-J8 package fits the PCB layout constraints and thermal management requirements.
