LP5907SNX variants from Texas Instruments
LP5907SNX Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
LP5907SNX is a Texas Instruments order-code family — not a single orderable MPN. This page lists 10 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.
1.8V LDO Regulator, 250mA, Low Noise, High PSRR, 2% Acc Other listed variants describe: 250-mA, low-noise, high-PSRR, ultra-low-dropout voltage regulator with low IQ and enable 4-X2SON -40 to 125; 2.8V LDO Regulator, 250mA, Low Noise, High PSRR, 120mV Dropout, 4-X2SON.
Suffix examples in this family: 1.8/NOPB, 2.5/NOPB, 2.75, 2.8/NOPB, 2.85/NOPB, 3.0/NOPB, 3.1/NOPB, 3.2/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: LP5907SNX-1.8/NOPB, LP5907SNX-2.5/NOPB, LP5907SNX-2.75, LP5907SNX-2.8/NOPB, LP5907SNX-2.85/NOPB, LP5907SNX-3.0/NOPB.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 10 distinct suffix patternsExamples: 1.8/NOPB, 2.5/NOPB, 2.75, 2.8/NOPB, 2.85/NOPB (+5 more). Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — 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 LP5907SNX map to package, grade, and reel options.
LP5907SNX 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: 1.8/NOPB, 2.5/NOPB, 2.75, 2.8/NOPB, 2.85/NOPB, 3.0/NOPB, 3.1/NOPB, 3.2/NOPB, 3.3/NOPB, 4.0/NOPB.
Full MPN examples: LP5907SNX-1.8/NOPB, LP5907SNX-2.5/NOPB, LP5907SNX-2.75, LP5907SNX-2.8/NOPB, LP5907SNX-2.85/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 LP5907SNX Microcontrollers
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For LP5907SNX, 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 "LP5907SNX" — include the full suffix (e.g. 1.8/NOPB, 2.5/NOPB, 2.75). RFQ with reel/tube preference and required date code.
