Product details
Overview
LM4030BMFX-2.5/NOPB from Texas Instruments is an ultra-high precision shunt voltage reference delivering 2.5 V output with ±0.10% initial accuracy (B-grade), 20 ppm/°C temperature coefficient over −40°C to +125°C, 75 ppm thermal hysteresis, and 40 ppm long-term stability. It operates from 120 µA minimum shunt current up to 30 mA continuous, enabling high-accuracy system references in space-constrained data acquisition front-ends.
For engineers reviewing the LM4030BMFX-2.5/NOPB datasheet, LM4030BMFX-2.5/NOPB pinout, LM4030BMFX-2.5/NOPB application, or LM4030BMFX-2.5/NOPB equivalent, this page delivers verified specifications, SOT-23-5 terminal mapping, real-world use cases in test instrumentation and automotive sensor signal conditioning, and two validated alternative parts with documented performance trade-offs.
Technical Context
The LM4030BMFX-2.5/NOPB uses a bandgap-based shunt architecture optimized for minimal voltage drift across temperature extremes and thermal cycling. Its dynamic offset cancellation scheme actively compensates for silicon-level mismatches and board stress-induced shifts, directly enabling its 75 ppm thermal hysteresis and 40 ppm long-term stability despite the miniature SOT-23 package.
It functions as a two-terminal device requiring only an external series resistor (RZ) to set operating current, with no mandatory bypass capacitor-though stable with up to 10 µF. Its reverse dynamic impedance decreases with increasing shunt current, improving supply noise rejection and making it suitable for low-noise ADC reference designs where load current varies between 120 µA and 30 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.5 V nominal; enables direct interface with 2.5 V ADCs, DACs, and analog front-ends without level-shifting. |
| Initial Accuracy | ±0.10% (B-grade); ensures ≤2.5 mV absolute error at 25°C, critical for 12-bit+ measurement systems. |
| Temp Coefficient | 20 ppm/°C (−40°C to +125°C); limits worst-case drift to ±500 µV over full industrial range. |
| Thermal Hysteresis | 75 ppm; guarantees ≤188 µV repeatability error after eight −40°C/+125°C cycles. |
| Long-Term Stability | 40 ppm (1000 hrs @ 30°C); corresponds to <1 µV/year drift, supporting 10+ year product lifecycles. |
| Min Operating Current | 120 µA; allows ultra-low-power operation in battery-backed or energy-harvesting sensor nodes. |
| Max Continuous Shunt | 30 mA; supports high-current reference buffering and fast transient load handling without dropout. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.45 mm body, gull-wing leads, RoHS-compliant matte tin lead finish, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No connect | Must be left floating; internal disconnect prevents parasitic coupling or ESD path interference. |
| 2 | GND or N/C | Functional ground connection; if unused, must remain unconnected-not tied to GND unless required by layout. |
| 3 | No connect | Internally open; floating per datasheet; soldering to PCB pad is acceptable but electrically inert. |
| 4 | VREF | Active reference output node; connects directly to ADC REF+ or precision op-amp feedback network. |
| 5 | GND | Primary ground return; must be low-impedance path to system ground plane to minimize IR drop and noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| High immunity to board stress | Dynamic offset cancellation actively suppresses PCB mounting-induced voltage shift, preserving accuracy on FR4 and flex substrates. |
| Capable of 50 mA transients | Withstands short-duration load surges up to 50 mA (<1 s), enabling robust operation during ADC sampling bursts or digital switching events. |
| Stable without external capacitor | Operates reliably with zero external capacitance-eliminates BOM cost and layout area while maintaining regulation integrity. |
| Low 0.1–10 Hz noise | 105 µVPP noise bandwidth enables sub-LSB stability in 16-bit delta-sigma ADC applications without additional filtering. |
| Extended temperature range | Rated for −40°C to +125°C junction operation, qualifying for under-hood automotive, industrial motor control, and outdoor instrumentation. |

|---|---|---|---|
| LM4040C25IDBZR | 2.5 V, ±0.5% initial accuracy, 100 ppm/°C TC, SOT-23-3, 60 µA min current | Lower precision; suited for cost-sensitive 10–12-bit systems where 5 mV error is acceptable | Select when budget constraints outweigh accuracy needs and PCB space permits larger RZ resistor due to higher min current. |
| REF3025AIDBZR | 2.5 V, ±0.2% initial accuracy, 50 ppm/°C TC, SOT-23-3, 50 µA min current, 30 ppm long-term stability | Moderate precision; lower TC than LM4030C but higher than LM4030B; no thermal hysteresis spec provided | Choose for mid-tier accuracy with lower power consumption; verify thermal hysteresis behavior in cyclic environments before deployment. |

FAQ
What is the guaranteed initial accuracy of LM4030BMFX-2.5/NOPB?
The LM4030BMFX-2.5/NOPB is a B-grade device with guaranteed initial accuracy of ±0.10% at 25°C, corresponding to ±2.5 mV maximum deviation from nominal 2.5 V output. This specification is production-tested and ensured across the full operating temperature range per TI's SNVS552B datasheet.
Does LM4030BMFX-2.5/NOPB require an external capacitor to operate?
No, LM4030BMFX-2.5/NOPB is designed to operate stably without any external capacitor. It remains functional and well-regulated with zero external capacitance. A bypass capacitor up to 10 µF may be added to improve transient response and reduce broadband noise, but it is optional-not required for basic regulation.
What is the maximum continuous shunt current rating for LM4030BMFX-2.5/NOPB?
The LM4030BMFX-2.5/NOPB supports a maximum continuous shunt current of 30 mA, as specified in its Absolute Maximum Ratings and Operating Ratings tables. Exceeding this value risks thermal overload and permanent parametric shift; transient currents up to 50 mA are allowed for durations under 1 second.
How does thermal hysteresis impact LM4030BMFX-2.5/NOPB in cyclic temperature environments?
LM4030BMFX-2.5/NOPB exhibits 75 ppm typical thermal hysteresis after eight −40°C to +125°C cycles, meaning its 25°C output voltage may shift by up to ±188 µV upon returning to room temperature. This is measured and guaranteed-critical for applications like automotive ECUs where repeated thermal cycling occurs over product lifetime.
What are the pin 1 orientation and packaging details for LM4030BMFX-2.5/NOPB?
LM4030BMFX-2.5/NOPB uses SOT-23-5 (DBV) packaging with pin 1 located in quadrant Q3 per JEDEC tape-and-reel standards. It ships in large tape-and-reel format (3000 pcs/reel), 8.4 mm reel width, 4.0 mm pitch, and matte tin (SN) lead finish compliant with RoHS and MSL Level-1 (260°C peak reflow).
