Texas Instruments LP3985IM
LP3985IM variants from Texas Instruments
LP3985IM Overview
What changes between part numbers, and what to check before you lock the BOM — general-purpose circuits.
Key Features
- Footprint / package: SOT-23, SC-74A, SOT-753Land pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 6 distinct suffix patternsExamples: 5-5.0/NOPB, 5-2.9/NOPB, 5-3.0/NOPB, 5-3.2/NOPB, 5-3.3/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

How to Choose the Right LP3985IM Variant
Match the footprint first
Packages here: SOT-23, SC-74A, SOT-753. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LP3985IM, 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 "LP3985IM" — include the full suffix (e.g. 5-5.0/NOPB, 5-2.9/NOPB, 5-3.0/NOPB). RFQ with reel/tube preference and required date code.
