Texas Instruments LP3873ES
LP3873ES variants from Texas Instruments
LP3873ES Overview
What changes between part numbers, and what to check before you lock the BOM — Integrated Circuits (ICs).
Key Features
- Footprint / package: TO-263-6, D²Pak (5 Leads + Tab), TO-263BASingle 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: 2.5/NOPB, 1.8/NOPB, 5.0/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 3 LP3873ES 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 |
|---|---|---|---|---|---|---|---|
| LP3873ES-2.5/NOPB | Package: TO-263-6, D²Pak (5 Leads + Tab), TO-263BA | Mounting Type: Surface Mount | Operating Temperature: -40°C ~ 125°C | Output Type: Fixed | Voltage Input Max: 7V | Supplier Device Package: DDPAK/TO-263-5 | TO-263-6, D²Pak (5 Leads + Tab), TO-263BA | Texas Instruments | Active | Compliant | In Stock | |
| LP3873ES-1.8/NOPB | 1.8V 3A LDO Regulator, TO-263, Power Good, 125°C | - | Texas Instruments | Active | Compliant | In Stock | |
| LP3873ES-5.0/NOPB | 3A LDO 5V Fixed Output, TO-263, Power Good, Enable | - | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right LP3873ES Integrated Circuits (ICs)
Match the footprint first
Packages here: TO-263-6, D²Pak (5 Leads + Tab), TO-263BA. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LP3873ES, 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 "LP3873ES" — include the full suffix (e.g. 2.5/NOPB, 1.8/NOPB, 5.0/NOPB). RFQ with reel/tube preference and required date code.
