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

Verify the specific suffix 'E2' against the manufacturer's latest datasheet to confirm RoHS compliance status and exact pinout configuration. Ensure the ordering code matches the required surface-mount package variant. Cross-reference the part number with official ROHM documentation to validate availability and any potential design-in restrictions or lifecycle changes.

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

Select this component when a fixed 18V output at up to 1A is required in a compact surface-mount form factor. Consider the thermal performance of the TO-252-3 package relative to the expected power dissipation. Verify that the input voltage remains within the specified 21V to 33V window to ensure stable regulation and prevent damage.

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

This regulator belongs to the BA178xx series, which offers surface-mount alternatives to traditional through-hole linear regulators. The series is characterized by robust protection features and wide application versatility across various electronic devices requiring reliable fixed voltage generation.

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

Direct substitutes include other 18V fixed linear regulators in the TO-252-3 package from compatible manufacturers, provided they meet the 1A current rating and input voltage specifications.
