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

Verify the specific suffix E2 against the official datasheet to confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the TO-252-3 package variant matches the target PCB footprint requirements. Confirm that the fixed 3V output aligns precisely with the system's voltage rail needs before finalizing procurement.

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

Select this component when a fixed 3V supply is required with moderate current demands up to 500mA. The TO-252-3 package offers a balance between thermal performance and board space efficiency. Consider the 2.3V minimum input voltage constraint to ensure sufficient headroom for the desired load current and dropout characteristics.
