Texas Instruments LM79L
LM79L variants from Texas Instruments
LM79L Overview
What changes between part numbers, and what to check before you lock the BOM — general-purpose circuits.
Key Features
- Footprint / package: SOICSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 6 distinct suffix patternsExamples: 15ACM/NOPB, 05ACMX/NOPB, 05ACTL/NOPB, 05ACTLX/NOPB, 12ACMX/NOPB (+1 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- general-purpose circuits — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 6 LM79L part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

Ordering Code Differences
How suffixes on LM79L map to package, grade, and reel options.
How to Choose the Right LM79L Variant
Match the footprint first
Packages here: SOIC. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LM79L, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "LM79L" — include the full suffix (e.g. 15ACM/NOPB, 05ACMX/NOPB, 05ACTL/NOPB). RFQ with reel/tube preference and required date code.
