Texas Instruments LM25117QPSQ
LM25117QPSQ variants from Texas Instruments
LM25117QPSQ Overview
What changes between part numbers, and what to check before you lock the BOM — DC DC Switching Regulators.
LM25117QPSQ is a Texas Instruments order-code family — not a single orderable MPN. This page lists 4 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Package: WQFN EP | Mounting Type: Surface Mount | Operating Supply Voltage: 4.5 to 42V | Output Voltage: 0.8 to 41V | Number of Outputs: 1 | Max Operating Temp: 125°C | Min Operating Temp: -40°C Other listed variants describe: Automotive Grade 4.5-42V Wide Vin, Current Mode Synchronous Buck Controller with Tracking 24-WQFN -40 to 125.
Across listed variants, watch these parameters: packages: WQFN EP.
Suffix examples in this family: NOPB, E/NOPB, X/NOPB. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: LM25117QPSQ, LM25117QPSQ/NOPB, LM25117QPSQE/NOPB, LM25117QPSQX/NOPB.
Key Features
- Footprint / package: WQFN EPSingle 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.
- 3 distinct suffix patternsExamples: NOPB, E/NOPB, X/NOPB. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- DC DC Switching Regulators — 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 Code Differences
How suffixes on LM25117QPSQ map to package, grade, and reel options.
LM25117QPSQ uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: NOPB, E/NOPB, X/NOPB.
Full MPN examples: LM25117QPSQ/NOPB, LM25117QPSQE/NOPB, LM25117QPSQX/NOPB.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right LM25117QPSQ DC DC Switching Regulators
Match the footprint first
Packages here: WQFN EP. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LM25117QPSQ, 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 "LM25117QPSQ" — include the full suffix (e.g. NOPB, E/NOPB, X/NOPB). RFQ with reel/tube preference and required date code.
