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

Verify the specific suffix E2 against official ROHM documentation to confirm RoHS compliance status and lead time constraints. Confirm that the TO-220CP-3 package designation matches your PCB footprint requirements. Check for any updated lifecycle notices as this component may be subject to discontinuation schedules. Ensure input voltage limits are respected to maintain safe operation within the specified 22 W power dissipation rating.

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

Select this component when a fixed 15 V output at 1 A is required using a through-hole topology. The TO-220CP-3 package offers robust thermal performance suitable for moderate power applications. Consider the 17.5 V minimum input requirement to ensure adequate dropout voltage margin. Verify that the 1 A current capacity meets the load demands without exceeding the thermal limits defined in the datasheet.
