Product details
Overview
LM4130CIM5-2.0 from National Semiconductor is a precision micropower low-dropout voltage reference delivering 2.048 V output with ±0.1% initial accuracy, 20 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 LM4130CIM5-2.0 datasheet, LM4130CIM5-2.0 pinout, LM4130CIM5-2.0 application, or LM4130CIM5-2.0 equivalent, key selection criteria include guaranteed full-accuracy operation from −40°C to +85°C, no required output capacitor, 75 µA quiescent current, and SOT23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The LM4130CIM5-2.0 implements a CMOS bandgap architecture with EEPROM-based curvature, tempco, and accuracy correction - enabling package-level programming to compensate for assembly-induced voltage shifts. This eliminates laser trimming while matching bipolar reference performance.
It operates as a series-connected, three-terminal voltage reference with internal compensation for stable operation across 0–100 µF capacitive loads and up to 20 mA output current. Line regulation is specified at 75 ppm/V (for VIN ≥ VREF + 300 mV), and load regulation is 32 ppm/mA over 0–20 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.048 V ±0.1% at 25°C - enables precise 12-bit ADC full-scale calibration without external trimming |
| Tempco | 20 ppm/°C max (−40°C to +85°C) - ensures ≤±1.68 mV total drift over industrial temperature range |
| Dropout Voltage | 275 mV @ 10 mA - supports regulation from 2.323 V supply, critical for single-cell Li-ion or coin-cell applications |
| Quiescent Current | 75 µA max - allows >1-year battery life in 10 µA-average-power IoT sensor nodes |
| Output Noise | 125 µVPP (0.1 Hz–10 Hz) - preserves SNR in 16-bit+ precision measurement front-ends |
| Load Capability | 20 mA source current - drives ADC reference inputs, op-amp bias networks, and DAC references directly |
| Line Regulation | 75 ppm/V - maintains <±0.15 mV error with ±1 V input variation, easing LDO selection upstream |
Pinout & Package
SOT23-5 surface-mount package with 1.6 mm × 2.9 mm footprint and 0.95 mm height - optimized for automated placement and thermal performance in dense layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 4) | Positive supply input | Accepts 2.323 V to 5.5 V; bypassing with 0.1 µF improves PSRR and transient response |
| GND (Pin 2) | Ground reference | Low-impedance return path; must connect to clean analog ground plane |
| VREF (Pin 5) | Precision output | Delivers regulated 2.048 V; stable with 0–100 µF capacitive loads; sources up to 20 mA |
| NC (Pins 1, 3) | No connection | Internally terminated; must remain unconnected on PCB to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| No output capacitor required | Eliminates BOM cost and board area for stability - unlike most LDO references needing ≥1 µF |
| EEPROM-trimmed CMOS bandgap | Enables post-assembly calibration to achieve ±0.1% accuracy and 20 ppm/°C tempco without laser trimming |
| Low dropout (275 mV) | Permits operation from single 2.4 V supply - essential for energy-harvesting and ultra-low-voltage systems |
| Full accuracy over −40°C to +85°C | Guarantees 2.048 V ±0.1% across full industrial range - no derating or external compensation needed |
| Stable with 100 µF capacitive load | Supports direct driving of ADC sample-and-hold capacitors and filtering networks without phase-margin risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| REF3020AIDBZR | 2.048 V, ±0.2% initial accuracy, 50 ppm/°C tempco, 50 µA IQ, SOT23-3 | Lacks NC pins and VIN/GND separation; requires external decoupling; lower accuracy grade | Select when lowest quiescent current (50 µA) is prioritized over tempco and accuracy |
| ADR3420ARJZ-R7 | 2.048 V, ±0.1% initial accuracy, 10 ppm/°C tempco, 120 µA IQ, SOT23-5 | Higher IQ and tighter tempco; uses different trimming method; not drop-in compatible due to different pin 1/3 NC behavior | Select when 10 ppm/°C tempco is mandatory and 45 µA higher IQ is acceptable |
Compared with REF3020AIDBZR and ADR3420ARJZ-R7, the LM4130CIM5-2.0 offers optimal balance of 20 ppm/°C tempco, ±0.1% accuracy, and 75 µA IQ in a proven SOT23-5 layout - making it preferred for industrial data loggers and portable test equipment where long-term stability and no-output-capacitor operation are design-critical.

FAQ
What is the operating temperature range for the LM4130CIM5-2.0?
The LM4130CIM5-2.0 is specified for full accuracy operation from −40°C to +85°C. It supports extended operation up to +125°C, though initial accuracy and tempco specifications are not guaranteed beyond +85°C. Thermal hysteresis is limited to 50 ppm over the −40°C to +125°C cycle, ensuring repeatability in cyclic environments.
Does the LM4130CIM5-2.0 require an output capacitor?
No, the LM4130CIM5-2.0 is explicitly designed to operate stably without any output capacitor and remains stable with capacitive loads from 0 to 100 µF. Adding an output capacitor improves load transient response but increases turn-on time - a trade-off documented in the application information section of the datasheet.
What is the maximum load current the LM4130CIM5-2.0 can source?
The LM4130CIM5-2.0 can source up to 20 mA while maintaining output voltage regulation within specification. At 10 mA load, dropout is guaranteed ≤275 mV; at 20 mA, typical dropout rises to ~400 mV. Output impedance remains <1 Ω, supporting dynamic loads in precision analog circuits.
How does the LM4130CIM5-2.0 achieve its 20 ppm/°C temperature coefficient?
The LM4130CIM5-2.0 achieves its 20 ppm/°C tempco through EEPROM-based curvature correction applied to a CMOS bandgap core. This post-assembly calibration compensates for die-to-package stress effects that degrade tempco in plastic-packaged references - a key differentiator from laser-trimmed alternatives.
Is the LM4130CIM5-2.0 pin-compatible with other SOT23-5 voltage references?
The LM4130CIM5-2.0 uses standard SOT23-5 pinout (VIN=Pin4, GND=Pin2, VREF=Pin5, NC=Pin1/3), matching common industry layout practices. However, pin compatibility does not imply functional or electrical drop-in replacement - e.g., REF3020AIDBZR uses SOT23-3 and lacks dedicated VIN/GND pins, so PCB redesign is required.
