Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the S-L2980A34MC-TF-G is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 3.4V
• Output current rating of 150mA
• Maximum input voltage of 10V
• Voltage dropout specification of 0.14V @ 50mA
• Quiescent current of 1 µA
• PSRR of 65dB (1kHz)
• SOT-23-5 package configuration
• Operating temperature range of -40°C ~ 85°C
• ROHS3 compliance and MSL Level 1 rating

The S-L2980A34MC-TF-U meets all these criteria and qualifies as a parametric equivalent. The primary distinction between these parts is product status and packaging designation (TF-G versus TF-U), not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The S-L2980A34MC-TF-U is the direct substitute for the S-L2980A34MC-TF-G. Both parts are manufactured by ABLIC Inc. and share identical electrical specifications and package configuration. The S-L2980A34MC-TF-U carries Active product status, making it suitable for new designs and ongoing production. Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. Selection between these parts should be based on availability and product lifecycle requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the S-L2980A34MC-TF-U directly replace the S-L2980A34MC-TF-G in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The S-L2980A34MC-TF-U operates at the same output voltage (3.4V), current rating (150mA), and dropout voltage (0.14V @ 50mA). Package configuration, pin assignment, and thermal characteristics are identical. No circuit modifications are required.

Q: What is the difference between the TF-G and TF-U packaging designations?

A: The designations indicate different packaging or distribution batches from ABLIC Inc. Both parts use SOT-23-5 package configuration and Tape & Reel delivery format. The electrical and mechanical specifications are identical.

Q: Why is the S-L2980A34MC-TF-G marked "Not For New Designs"?

A: This status indicates the part has reached end-of-life in ABLIC Inc.'s product portfolio. The S-L2980A34MC-TF-U, with Active status, is the recommended choice for new system implementations and ongoing production.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating. Regulatory and environmental compliance is identical.

Q: What is the minimum input voltage required for proper operation?

A: The specifications provided define maximum input voltage (10V) and dropout voltage (0.14V @ 50mA). Minimum input voltage is not specified in the provided parameters and cannot be determined from the available data.
