Substitute Part Grouping Explanation

Substitution for the S-L2980A55MC-TF-G is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 5.5V
• Output current rating of 150mA
• Maximum input voltage of 10V
• Dropout voltage specification of 0.14V @ 50mA
• Quiescent current of 1 µA
• SOT-23-5 package configuration
• Operating temperature range of -40°C to 85°C
• Enable control feature
• ROHS3 compliance and REACH unaffected status

The substitute part S-L2980A55MC-TF-U meets all these electrical and mechanical parameters identically, differing only in product status and packaging tape configuration.

Parameter Comparison
