Texas Instruments LP3988IMF
LP3988IMF variants from Texas Instruments
LP3988IMF Overview
What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).
Key Features
- Footprint / package: SC-74A, SOT-753Single 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.
- 2 distinct suffix patternsExamples: 3.0/NOPB, 2.5/NOPB. 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
Ordering Variants
Compare 2 LP3988IMF part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| LP3988IMF-3.0/NOPB | Package: SC-74A, SOT-753 | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C | Output Type: Fixed | Voltage Input Max: 6V | Supplier Device Package: SOT-23-5 | SC-74A, SOT-753 | Texas Instruments | Active | Compliant | In Stock | |
| LP3988IMF-2.5/NOPB | 2.5V LDO 150mA, SOT-23, Low Dropout Voltage Regulator | - | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right LP3988IMF Integrated Circuits (ICs)
Match the footprint first
Packages here: 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 LP3988IMF, 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 "LP3988IMF" — include the full suffix (e.g. 3.0/NOPB, 2.5/NOPB). RFQ with reel/tube preference and required date code.
