Product details
Overview
LM4130AIM5-2.5/NOPB from Texas Instruments is a precision micropower low-dropout voltage reference IC delivering 2.500 V output with ±0.05% initial accuracy, 10 ppm/°C temperature coefficient, and ≤275 mV dropout at 10 mA-designed for high-stability analog signal chains in portable instrumentation and battery-powered data acquisition systems.
For engineers reviewing the LM4130AIM5-2.5/NOPB datasheet, LM4130AIM5-2.5/NOPB pinout, LM4130AIM5-2.5/NOPB application, or LM4130AIM5-2.5/NOPB equivalent, key selection criteria include guaranteed −40°C to +85°C full-accuracy operation, no required output capacitor, and SOT23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The LM4130AIM5-2.5/NOPB uses EEPROM-trimmed CMOS bandgap architecture to correct curvature, tempco, and initial accuracy at package level-enabling laser-trimmed performance without laser trimming. Its internal correction eliminates post-assembly calibration drift common in plastic-packaged references.
This device operates as a series (two-terminal) voltage reference with active regulation, requiring only VIN, GND, and VREF connections. It achieves stable regulation with capacitive loads up to 100 µF and delivers 20 mA output current while maintaining <1 Ω output impedance and 150 µVPP (0.1–10 Hz) noise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500 V ±0.05% (A-grade initial accuracy ensures ≤1.25 mV absolute error at 25°C) |
| Tempco | 10 ppm/°C (max over −40°C to +85°C; enables ≤2.1 mV total drift across full range) |
| Dropout Voltage | ≤275 mV @ 10 mA (supports regulation from 2.775 V input, critical for single-cell Li-ion systems) |
| Supply Current | ≤75 μA (enables >1-year battery life in 10-μA sleep-mode sensor nodes) |
| Load Regulation | 25–60 ppm/mA (0–20 mA load change induces ≤0.5 mV output shift) |
| Line Regulation | 30 ppm/V (input variation from VREF+200 mV to 5.5 V causes ≤0.075 mV output change) |
| Output Noise | 150 μVPP (0.1–10 Hz; supports 16-bit ADCs without external filtering) |
Pinout & Package
SOT23-5 surface-mount package (2.92 mm × 1.6 mm × 1.1 mm), lead-free and RoHS-compliant per /NOPB suffix. Five-terminal configuration with two NC pins enabling compact layout and reduced parasitic coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | No Connection | Internally terminated; must remain unconnected to avoid parasitic leakage paths |
| Pin 2 | Ground | Primary return path for reference core and load current; requires low-impedance PCB connection |
| Pin 3 | No Connection | Internally terminated; floating connection prevents ESD-induced voltage shifts |
| Pin 4 | Positive Supply (VIN) | Input supply pin; bypassing with 0.1 µF capacitor improves transient rejection and stability |
| Pin 5 | Reference Output (VREF) | Regulated 2.500 V output capable of sourcing up to 20 mA; stable without output capacitor |
Key Features
| Feature | Design Value |
|---|---|
| EEPROM-based trimming | Enables post-assembly correction of tempco and accuracy-eliminates laser-trimming cost while achieving A-grade specs |
| Capacitor-free operation | Stable with 0 µF output capacitance, removing BOM cost and board area for decoupling caps in ultra-low-power designs |
| Low dropout voltage | 275 mV max at 10 mA allows use with 2.8 V supply rails-critical for modern low-voltage microcontrollers and sensors |
| Full-temperature accuracy | Guaranteed ±0.05% and 10 ppm/°C over −40°C to +85°C-not just typical or 25°C-only specs |
| High output drive | 20 mA sourcing capability enables direct driving of ADC references, op-amp bias networks, and DAC supplies |

FAQ
What is the guaranteed initial accuracy and temperature coefficient of the LM4130AIM5-2.5/NOPB?
The LM4130AIM5-2.5/NOPB is an A-grade device with guaranteed ±0.05% initial accuracy and 10 ppm/°C maximum temperature coefficient over −40°C to +85°C. These values are production-tested and ensured-not typical or 25°C-only specifications-and reflect the EEPROM-trimmed performance that distinguishes this variant within the LM4130 family.
Does the LM4130AIM5-2.5/NOPB require an output capacitor for stability?
No, the LM4130AIM5-2.5/NOPB is designed to operate stably without any output capacitor and remains stable with capacitive loads up to 100 µF. This eliminates BOM cost and PCB area for decoupling, simplifying design in ultra-low-power and space-constrained applications where the LM4130AIM5-2.5/NOPB is commonly deployed.
What is the maximum load current and dropout voltage specification for the LM4130AIM5-2.5/NOPB?
The LM4130AIM5-2.5/NOPB delivers up to 20 mA output current with ≤275 mV dropout voltage at 10 mA load. This low dropout enables reliable operation from supply rails as low as 2.775 V, supporting single-cell Li-ion and 3.0 V system designs where the LM4130AIM5-2.5/NOPB serves as the primary reference for ADCs and precision analog circuitry.
How does the EEPROM trimming in the LM4130AIM5-2.5/NOPB improve performance versus laser-trimmed references?
The LM4130AIM5-2.5/NOPB uses on-chip EEPROM registers to correct curvature, tempco, and initial accuracy after packaging-compensating for assembly-induced shifts that degrade laser-trimmed devices in plastic SOT23-5 packages. This yields laser-grade performance (±0.05%, 10 ppm/°C) at CMOS cost, a key advantage confirmed in TI's SNVS048D datasheet for the LM4130AIM5-2.5/NOPB.
Is the LM4130AIM5-2.5/NOPB suitable for automotive or extended-temperature applications?
The LM4130AIM5-2.5/NOPB is specified for −40°C to +85°C operation with full accuracy guarantees, meeting industrial and many automotive cabin applications. While it supports extended operation to +125°C, the A-grade accuracy and tempco specs are not ensured above +85°C-so for under-hood automotive use, designers should verify system-level drift budgets or consider automotive-qualified alternatives.
