LM79L05ACTL Equivalent & Substitute Parts

Part Overview

The LM79L05ACTL is a linear voltage regulator IC from Texas Instruments designed to provide a fixed negative 5V output at 100mA. This Surface Mount device in 6-DSBGA packaging is classified as Obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. The part delivers regulated negative voltage with integrated over-temperature and short-circuit protection, suitable for applications requiring stable negative rail generation in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LM79L05ACTL are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Output Configuration: Negative
• Output Type: Fixed
• Voltage - Output (Min/Fixed): -5V
• Current - Output: 100mA
• Voltage - Input (Max): -35V
• Current - Quiescent (Iq): 6 mA
• PSRR: 50dB (120Hz)
• Protection Features: Over Temperature, Short Circuit
• Operating Temperature: 0°C ~ 70°C
• Mounting Type: Surface Mount
• Package / Case: 6-WFBGA, DSBGA
• Supplier Device Package: 6-DSBGA (1.5x1.3)
• Base Product Number: LM79L05

All identified substitute parts maintain identical electrical performance and mechanical compatibility with the main part number. Variations in packaging format (Tape & Reel versus bulk) and product status do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The LM79L05ACTL is classified as Obsolete. Both substitute parts—LM79L05ACTL/NOPB and LM79L05ACTLX/NOPB—are Active products from Texas Instruments and maintain complete electrical and mechanical equivalence.

Compliance Advantage: The substitute parts carry ROHS3 Compliant certification, whereas the main part is RoHS non-compliant. For applications subject to RoHS regulations or environmental compliance requirements, either substitute part is the appropriate selection.

Packaging Consideration: Both substitutes are supplied in Tape & Reel (TR) format, standard for production environments. The main part inventory is available in bulk form. Selection between LM79L05ACTL/NOPB and LM79L05ACTLX/NOPB depends on procurement quantity and supply chain requirements, as both are functionally identical.

Frequently Asked Questions (FAQ)

Q: Can LM79L05ACTL/NOPB and LM79L05ACTLX/NOPB be used interchangeably with LM79L05ACTL?

A: Yes. All three part numbers are functionally equivalent. They deliver identical electrical performance: -5V fixed output, 100mA current capacity, -35V maximum input, 50dB PSRR at 120Hz, and integrated thermal and short-circuit protection. Pin configuration, package dimensions (6-DSBGA 1.5x1.3), and mounting type are identical.

Q: What is the difference between the substitute parts?

A: LM79L05ACTL/NOPB and LM79L05ACTLX/NOPB are electrically and mechanically identical. Both are Active products with ROHS3 compliance. The difference is in the suffix designation (ACTL/NOPB versus ACTLX/NOPB), which reflects manufacturing or qualification variations. Both are suitable for direct substitution.

Q: Why is the main part marked Obsolete?

A: The LM79L05ACTL is classified as Obsolete by Texas Instruments. The Active substitute parts (LM79L05ACTL/NOPB and LM79L05ACTLX/NOPB) represent the current product line continuation and are recommended for new designs and ongoing production.

Q: Are there any compliance differences I should consider?

A: Yes. The main part is RoHS non-compliant, while both substitute parts are ROHS3 Compliant. If your application or market requires RoHS compliance, use either substitute part. All three parts are REACH Unaffected and carry the same ECCN and HTSUS classifications.

Q: Does packaging format affect electrical performance?

A: No. The main part is available in bulk packaging, while substitutes are supplied in Tape & Reel format. This is a procurement and handling consideration only. Electrical specifications and performance are identical.

Q: Can I use these parts in high-temperature applications?

A: The operating temperature range for all three parts is 0°C to 70°C. Applications requiring operation outside this range require alternative components.
