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

Verify the specific suffix CE2 against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure compatibility with AEC-Q100 requirements if used in automotive contexts. Cross-reference the TO-252-3 footprint dimensions during PCB layout. Confirm RoHS compliance status through the latest product specification documents before finalizing procurement orders.

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

Select this component when designing circuits that require minimal static current draw from the power source. The fixed 3.3 V output eliminates the need for external resistive dividers. Verify that the expected load current remains below the 500 mA limit to ensure proper thermal management. Consider the dropout voltage characteristics relative to the minimum input voltage available in the system design.
