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

Verify the specific suffix 'CE2' or 'CTR' against the manufacturer's official datasheet to confirm exact packaging and tape-and-reel specifications. Ensure the ordering part number matches the required functional variant, as suffixes may indicate differences in shipping format rather than electrical performance. Cross-reference the RoHS status and functional safety classification directly with the latest documentation provided by ROHM Semiconductor.

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

Select this component when designing automotive power supplies requiring direct battery connection with low standby current. The adjustable output range suits flexible voltage requirements compared to fixed-output variants. Verify that the load current does not exceed 500mA and that the input voltage remains within the 42V maximum limit. Consider the HRP-5 package dimensions for PCB layout constraints and thermal dissipation needs in enclosed environments.

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

This device belongs to the BD800M5W series of low-dropout regulators optimized for automotive use. The series offers various packages including TO-252-J5 and TO-263-5, with the HRP-5 providing a compact surface-mount solution.
