Texas Instruments LP3470IM
LP3470IM variants from Texas Instruments
LP3470IM Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
LP3470IM is a Texas Instruments order-code family — not a single orderable MPN. This page lists 12 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.
Active-Low Reset IC, 2.63V Threshold, SOT-23, 5.5V Max Other listed variants describe: Reset IC, 2.75V Threshold, SOT-23-5, Active-Low; 2.83V Supervisory IC, SOT-23-5, Active Low Reset.
Suffix examples in this family: 5-2.63/NOPB, 5-2.75/NOPB, 5-2.83/NOPB, 5-3.65/NOPB, 5-4.00/NOPB, 5-4.63/NOPB, 5X-2.63/NOPB, 5X-2.83/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: LP3470IM5-2.63/NOPB, LP3470IM5-2.75/NOPB, LP3470IM5-2.83/NOPB, LP3470IM5-3.65/NOPB, LP3470IM5-4.00/NOPB, LP3470IM5-4.63/NOPB.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 12 distinct suffix patternsExamples: 5-2.63/NOPB, 5-2.75/NOPB, 5-2.83/NOPB, 5-3.65/NOPB, 5-4.00/NOPB (+7 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 LP3470IM map to package, grade, and reel options.
LP3470IM 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: 5-2.63/NOPB, 5-2.75/NOPB, 5-2.83/NOPB, 5-3.65/NOPB, 5-4.00/NOPB, 5-4.63/NOPB, 5X-2.63/NOPB, 5X-2.83/NOPB, 5X-2.93/NOPB, 5X-4.00/NOPB (+2 more).
Full MPN examples: LP3470IM5-2.63/NOPB, LP3470IM5-2.75/NOPB, LP3470IM5-2.83/NOPB, LP3470IM5-3.65/NOPB, LP3470IM5-4.00/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 LP3470IM 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 LP3470IM, 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 "LP3470IM" — include the full suffix (e.g. 5-2.63/NOPB, 5-2.75/NOPB, 5-2.83/NOPB). RFQ with reel/tube preference and required date code.
