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

Verify the complete part number including the 'G' suffix to ensure RoHS compliance as specified by the manufacturer. Confirm that the SC-82-4 package dimensions align with your PCB footprint requirements. Ensure the input voltage supply remains within the 4 V to 12 V operational limits to maintain proper regulation and prevent device damage during procurement and integration.

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

Select this component when a fixed 3.0 V rail is required with moderate current demands up to 80 mA. It is suitable for applications prioritizing low static current over ultra-low dropout performance. Consider the SC-82-4 package size constraints and the necessity for an active-high or active-low enable signal before finalizing the design choice.
