L78M Overview

What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).

Key Features

Footprint / package: TO-220-3Single 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.
14 distinct suffix patternsExamples: 12CV-DG, 05ABDT-TR, 05ABV, 05ACDT-TR, 08ABDT-TR (+9 more). Decode suffix meaning in the ordering notes under the variant table.

Target Applications

Integrated Circuits (ICs) — 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

How to Choose the Right L78M Integrated Circuits (ICs)

📦

Match the footprint first

Packages here: TO-220-3. Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For L78M, 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 "L78M" — include the full suffix (e.g. 12CV-DG, 05ABDT-TR, 05ABV). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the L78M product family.

Is L78M a single part I can order, or a family prefix?

L78M is a base / family code from STMicroelectronics. You order a full MPN such as L78M12CV-DG, L78M05ABDT-TR, L78M05ABV. The variant table lists 14 orderable lines with different suffixes.

What do the suffix letters on L78M part numbers mean?

Listed suffix fragments include: 12CV-DG, 05ABDT-TR, 05ABV, 05ACDT-TR, 08ABDT-TR, 08CDT-TR. Typically they encode package (TO-220-3), temperature grade, and tape/reel option. Always decode on the STMicroelectronics datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of L78M variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on L78M?

Full manufacturer MPN (not just L78M), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.
