Texas Instruments LM385BXZ
LM385BXZ variants from Texas Instruments
LM385BXZ Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: TO-226-3, TO-92-3 (TO-226AA)Single 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: 1.2/NOPB, NOPB. 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 Variants
Compare 2 LM385BXZ 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 |
|---|---|---|---|---|---|---|---|
| LM385BXZ-1.2/NOPB | 1.235-V, 0°C to 70°C, micropower voltage reference diode 3-TO-92 0 to 70 | - | Texas Instruments | Active | Compliant | In Stock | |
| LM385BXZ/NOPB | Package: TO-226-3, TO-92-3 (TO-226AA) | Mounting Type: Through Hole | Operating Temperature: 0°C ~ 70°C (TA) | Tolerance: ±1% | Temperature Coefficient: 30ppm/°C | Output Type: Adjustable | TO-226-3, TO-92-3 (TO-226AA) | Texas Instruments | Active | Compliant | In Stock |

How to Choose the Right LM385BXZ Microcontrollers
Match the footprint first
Packages here: TO-226-3, TO-92-3 (TO-226AA). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LM385BXZ, 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 "LM385BXZ" — include the full suffix (e.g. 1.2/NOPB, NOPB). RFQ with reel/tube preference and required date code.
