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

Verify the specific suffix 'MG' corresponds to the SC-70-5 package variant when sourcing. Confirm the '-2.0' designation matches the required 2.0 V fixed output voltage. Ensure the 'NOPB' suffix indicates lead-free and RoHS compliance as per manufacturer specifications. Cross-reference the datasheet revision date to ensure compatibility with current design requirements.

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

Select this component when a fixed 2.0 V rail is required with minimal footprint and low standby current. The SC-70-5 package offers space efficiency compared to larger SOT-23 variants. Consider the 150 mA output limit for load requirements. Verify input voltage stability remains above the minimum threshold of 1.8 V during operation.
